The Agents SDK now exports an
MCPConnectionStateenum that provides better type safety and consistency when working with MCP server connection states.Connection states are now available as enum constants instead of string literals:
TypeScript import { MCPConnectionState } from "agents";// Check connection states using enum constantsif (server.state === MCPConnectionState.READY) {console.log("Server is ready to use");}Available states:
MCPConnectionState.AUTHENTICATING- Waiting for OAuth authorization to completeMCPConnectionState.CONNECTING- Establishing transport connection to MCP serverMCPConnectionState.DISCOVERING- Discovering server capabilities (tools, resources, prompts)MCPConnectionState.READY- Fully connected and ready to useMCPConnectionState.FAILED- Connection failed at some point
If you were using string literals to check connection states, update your code:
Before if (server.state === "ready") {// Do something}After import { MCPConnectionState } from "agents";if (server.state === MCPConnectionState.READY) {// Do something}MCP client connections now use fail-fast behavior with
Promise.allinstead ofPromise.allSettled, providing quicker feedback when server capability discovery fails. The SDK also now only attempts to register capabilities that the server advertises, improving reliability and reducing unnecessary errors.The connection state machine has been refined:
- Non-OAuth servers:
CONNECTING→DISCOVERING→READY - OAuth servers:
AUTHENTICATING→ (callback) →CONNECTING→DISCOVERING→READY - Errors: Any state can transition to
FAILEDon error
- MCP server state broadcasts now occur before and after OAuth connection establishment, providing better real-time updates to connected clients
- Connection state is set to
FAILEDbefore throwing errors during capability discovery, ensuring proper state management

Containers and Sandboxes pricing for CPU time is now based on active usage only, instead of provisioned resources.
This means that you now pay less for Containers and Sandboxes.
Imagine running the
standard-2instance type for one hour, which can use up to 1 vCPU, but on average you use only 20% of your CPU capacity.CPU-time is priced at $0.00002 per vCPU-second.
Previously, you would be charged for the CPU allocated to the instance multiplied by the time it was active, in this case 1 hour.
CPU cost would have been: $0.072 — 1 vCPU * 3600 seconds * $0.00002
Now, since you are only using 20% of your CPU capacity, your CPU cost is cut to 20% of the previous amount.
CPU cost is now: $0.0144 — 1 vCPU * 3600 seconds * $0.00002 * 20% utilization
This can significantly reduce costs for Containers and Sandboxes.
See the documentation to learn more about Containers, Sandboxes, and associated pricing.

Until now, if a Worker had been previously deployed via the Cloudflare Dashboard ↗, a subsequent deployment done via the Cloudflare Workers CLI, Wrangler (through the
deploycommand), would allow the user to override the Worker's dashboard settings without providing details on what dashboard settings would be lost.Now instead,
wrangler deploypresents a helpful representation of the differences between the local configuration and the remote dashboard settings, and offers to update your local configuration file for you.See example below showing a before and after for
wrangler deploywhen a local configuration is expected to override a Worker's dashboard settings:After
Also, if instead Wrangler detects that a deployment would override remote dashboard settings but in an additive way, without modifying or removing any of them, it will simply proceed with the deployment without requesting any user interaction.
Update to Wrangler v4.50.0 or greater to take advantage of this improved deploy flow.

AI Search now supports custom HTTP headers for website crawling, solving a common problem where valuable content behind authentication or access controls could not be indexed.
Previously, AI Search could only crawl publicly accessible pages, leaving knowledge bases, documentation, and other protected content out of your search results. With custom headers support, you can now include authentication credentials that allow the crawler to access this protected content.
This is particularly useful for indexing content like:
- Internal documentation behind corporate login systems
- Premium content that requires users to provide access to unlock
- Sites protected by Cloudflare Access using service tokens
To add custom headers when creating an AI Search instance, select Parse options. In the Extra headers section, you can add up to five custom headers per Website data source.
For example, to crawl a site protected by Cloudflare Access, you can add service token credentials as custom headers:
CF-Access-Client-Id: your-token-id.accessCF-Access-Client-Secret: your-token-secretThe crawler will automatically include these headers in all requests, allowing it to access protected pages that would otherwise be blocked.
Learn more about configuring custom headers for website crawling in AI Search.

To facilitate significant enhancements to our submission processes, the Final Disposition column of the Team Submissions > Reclassifications page inside the Email Security Zero Trust application will be temporarily removed.
The column displaying the final disposition status for submitted email misses will no longer be visible on the specified page.
This temporary change is required as we revamp and integrate a more powerful backend infrastructure for processing these security-critical submissions. This update is designed to make even more effective use of the data you provide to improve our detection capabilities. We assure you that your submissions are continuing to be addressed at an even greater rate than before, fueling faster and more accurate security improvements.
Rest assured, the ability to submit email misses and the underlying analysis work remain fully operational. We are committed to reintroducing a refined, more valuable status update feature once the new infrastructure is completed.

The Zero Trust dashboard and navigation is receiving significant and exciting updates. The dashboard is being restructured to better support common tasks and workflows, and various pages have been moved and consolidated.
There is a new guided experience on login detailing the changes, and you can use the Zero Trust dashboard search to find product pages by both their new and old names, as well as your created resources. To replay the guided experience, you can find it in Overview > Get Started.
Notable changes
- Product names have been removed from many top-level navigation items to help bring clarity to what they help you accomplish. For example, you can find Gateway policies under ‘Traffic policies' and CASB findings under ‘Cloud & SaaS findings.'
- You can view all analytics, logs, and real-time monitoring tools from ‘Insights.'
- ‘Networks' better maps the ways that your corporate network interacts with Cloudflare. Some pages like Tunnels, are now a tab rather than a full page as part of these changes. You can find them at Networks > Connectors.
- Settings are now located closer to the tools and resources they impact. For example, this means you'll find your WARP configurations at Team & Resources > Devices.
No changes to our API endpoint structure or to any backend services have been made as part of this effort.

We've resolved a bug in Log Explorer that caused inconsistencies between the custom SQL date field filters and the date picker dropdown. Previously, users attempting to filter logs based on a custom date field via a SQL query sometimes encountered unexpected results or mismatching dates when using the interactive date picker.
This fix ensures that the custom SQL date field filters now align correctly with the selection made in the date picker dropdown, providing a reliable and predictable filtering experience for your log data. This is particularly important for users creating custom log views based on time-sensitive fields.
-
We've significantly enhanced Log Explorer by adding support for 14 additional Cloudflare product datasets.
This expansion enables Operations and Security Engineers to gain deeper visibility and telemetry across a wider range of Cloudflare services. By integrating these new datasets, users can now access full context to efficiently investigate security incidents, troubleshoot application performance issues, and correlate logged events across different layers (like application and network) within a single interface. This capability is crucial for a complete and cohesive understanding of event flows across your Cloudflare environment.
The newly supported datasets include:
Dns_logsNel_reportsPage_shield_eventsSpectrum_eventsZaraz_events
Audit LogsAudit_logs_v2Biso_user_actionsDNS firewall logsEmail_security_alertsMagic Firewall IDSNetwork AnalyticsSinkhole HTTPipsec_logs
You can now use Log Explorer to query and filter with each of these datasets. For example, you can identify an IP address exhibiting suspicious behavior in the
FW_eventlogs, and then instantly pivot to theNetwork Analyticslogs orAccesslogs to see its network-level traffic profile or if it bypassed a corporate policy.To learn more and get started, refer to the Log Explorer documentation and the Cloudflare Logs documentation.
-
Digital Experience Monitoring (DEX) provides visibility into WARP device metrics, connectivity, and network performance across your Cloudflare SASE deployment.
We've released four new WARP and DEX device data sets that can be exported via Cloudflare Logpush. These Logpush data sets can be exported to R2, a cloud bucket, or a SIEM to build a customized logging and analytics experience.
To create a new DEX or WARP Logpush job, customers can go to the account level of the Cloudflare dashboard > Analytics & Logs > Logpush to get started.

Starting February 2, 2026, the
cloudflared proxy-dnscommand will be removed from all newcloudflaredreleases.This change is being made to enhance security and address a potential vulnerability in an underlying DNS library. This vulnerability is specific to the
proxy-dnscommand and does not affect any othercloudflaredfeatures, such as the core Cloudflare Tunnel service.The
proxy-dnscommand, which runs a client-side DNS-over-HTTPS (DoH) proxy, has been an officially undocumented feature for several years. This functionality is fully and securely supported by our actively developed products.Versions of
cloudflaredreleased before this date will not be affected and will continue to operate. However, note that our official support policy for anycloudflaredrelease is one year from its release date.We strongly advise users of this undocumented feature to migrate to one of the following officially supported solutions before February 2, 2026, to continue benefiting from secure DNS-over-HTTPS.
The preferred method for enabling DNS-over-HTTPS on user devices is the Cloudflare WARP client. The WARP client automatically secures and proxies all DNS traffic from your device, integrating it with your organization's Zero Trust policies and posture checks.
For scenarios where installing a client on every device is not possible (such as servers, routers, or IoT devices), we recommend using the WARP Connector.
Instead of running
cloudflared proxy-dnson a machine, you can install the WARP Connector on a single Linux host within your private network. This connector will act as a gateway, securely routing all DNS and network traffic from your entire subnet to Cloudflare for filtering and logging.

We're excited to announce a quality-of-life improvement for Log Explorer users. You can now resize the custom SQL query window to accommodate longer and more complex queries.
Previously, if you were writing a long custom SQL query, the fixed-size window required excessive scrolling to view the full query. This update allows you to easily drag the bottom edge of the query window to make it taller. This means you can view your entire custom query at once, improving the efficiency and experience of writing and debugging complex queries.
To learn more and get started, refer to the Log Explorer documentation.

We’re excited to introduce Logpush Health Dashboards, giving customers real-time visibility into the status, reliability, and performance of their Logpush jobs. Health dashboards make it easier to detect delivery issues, monitor job stability, and track performance across destinations. The dashboards are divided into two sections:
-
Upload Health: See how much data was successfully uploaded, where drops occurred, and how your jobs are performing overall. This includes data completeness, success rate, and upload volume.
-
Upload Reliability – Diagnose issues impacting stability, retries, or latency, and monitor key metrics such as retry counts, upload duration, and destination availability.
Health Dashboards can be accessed from the Logpush page in the Cloudflare dashboard at the account or zone level, under the Health tab. For more details, refer to our Logpush Health Dashboards documentation, which includes a comprehensive troubleshooting guide to help interpret and resolve common issues.

We have previously added new application categories to better reflect their content and improve HTTP traffic management: refer to Changelog. While the new categories are live now, we want to ensure you have ample time to review and adjust any existing rules you have configured against old categories. The remapping of existing applications into these new categories will be completed by January 30, 2026. This timeline allows you a dedicated period to:
- Review the new category structure.
- Identify any policies you have that target the older categories.
- Adjust your rules to reference the new, more precise categories before the old mappings change. Once the applications have been fully remapped by January 30, 2026, you might observe some changes in the traffic being mitigated or allowed by your existing policies. We encourage you to use the intervening time to prepare for a smooth transition.

We're excited to announce that Log Explorer users can now cancel queries that are currently running.
This new feature addresses a common pain point: waiting for a long, unintended, or misconfigured query to complete before you can submit a new, correct one. With query cancellation, you can immediately stop the execution of any undesirable query, allowing you to quickly craft and submit a new query, significantly improving your investigative workflow and productivity within Log Explorer.
-
We're excited to announce a new feature in Log Explorer that significantly enhances how you analyze query results: the Query results distribution chart.
This new chart provides a graphical distribution of your results over the time window of the query. Immediately after running a query, you will see the distribution chart above your result table. This visualization allows Log Explorer users to quickly spot trends, identify anomalies, and understand the temporal concentration of log events that match their criteria. For example, you can visually confirm if a spike in traffic or errors occurred at a specific time, allowing you to focus your investigation efforts more effectively. This feature makes it faster and easier to extract meaningful insights from your vast log data.
The chart will dynamically update to reflect the logs matching your current query.

Workers, including those using Durable Objects and Browser Rendering, may now process WebSocket messages up to 32 MiB in size. Previously, this limit was 1 MiB.
This change allows Workers to handle use cases requiring large message sizes, such as processing Chrome Devtools Protocol messages.
For more information, please see the Durable Objects startup limits.
-
We've raised the Cloudflare Workflows account-level limits for all accounts on the Workers paid plan:
- Instance creation rate increased from 100 workflow instances per 10 seconds to 100 instances per second
- Concurrency limit increased from 4,500 to 10,000 workflow instances per account
These increases mean you can create new instances up to 10x faster, and have more workflow instances concurrently executing. To learn more and get started with Workflows, refer to the getting started guide.
If your application requires a higher limit, fill out the Limit Increase Request Form or contact your account team. Please refer to Workflows pricing for more information.

Two-factor authentication (2FA) is one of the best ways to protect your account from the risk of account takeover. Cloudflare has offered phishing resistant 2FA options including hardware based keys (for example, a Yubikey) and app based TOTP (time-based one-time password) options which use apps like Google or Microsoft's Authenticator app. Unfortunately, while these solutions are very secure, they can be lost if you misplace the hardware based key, or lose the phone which includes that app. The result is that users sometimes get locked out of their accounts and need to contact support.
Today, we are announcing the addition of email as a 2FA factor for all Cloudflare accounts. Email 2FA is in wide use across the industry as a least common denominator for 2FA because it is low friction, loss resistant, and still improves security over username/password login only. We also know that most commercial email providers already require 2FA, so your email address is usually well protected already.
You can now enable email 2FA on the Cloudflare dashboard:
- Go to Profile at the top right corner.
- Select Authentication.
- Under Two-Factor Authentication, select Set up.
Cloudflare is critical infrastructure, and you should protect it as such. Review the following best practices and make sure you are doing your part to secure your account:
- Use a unique password for every website, including Cloudflare, and store it in a password manager like 1Password or Keeper. These services are cross-platform and simplify the process of managing secure passwords.
- Use 2FA to make it harder for an attacker to get into your account in the event your password is leaked.
- Store your backup codes securely. A password manager is the best place since it keeps the backup codes encrypted, but you can also print them and put them somewhere safe in your home.
- If you use an app to manage your 2FA keys, enable cloud backup, so that you don't lose your keys in the event you lose your phone.
- If you use a custom email domain to sign in, configure SSO.
- If you use a public email domain like Gmail or Hotmail, you can also use social login with Apple, GitHub, or Google to sign in.
- If you manage a Cloudflare account for work:
- Have at least two administrators in case one of them unexpectedly leaves your company.
- Use SCIM to automate permissions management for members in your Cloudflare account.
-
As Cloudflare's platform has grown, so has the need for precise, role-based access control. We’ve redesigned the Member Management experience in the Dashboard to help administrators more easily discover, assign, and refine permissions for specific principals.
Refreshed member invite flow
We overhauled the Invite Members UI to simplify inviting users and assigning permissions.
Refreshed Members Overview Page
We've updated the Members Overview Page to clearly display:
- Member 2FA status
- Which members hold Super Admin privileges
- API access settings per member
- Member onboarding state (accepted vs pending invite)
New Member Permission Policies Details View
We've created a new member details screen that shows all permission policies associated with a member; including policies inherited from group associations to make it easier for members to understand the effective permissions they have.
Improved Member Permission Workflow
We redesigned the permission management experience to make it faster and easier for administrators to review roles and grant access.
Account-scoped Policies Restrictions Relaxed
Previously, customers could only associate a single account-scoped policy with a member. We've relaxed this restriction, and now Administrators can now assign multiple account-scoped policies to the same member; bringing policy assignment behavior in-line with user-groups and providing greater flexibility in managing member permissions.

Cloudflare now provides two new request fields in the Ruleset engine that let you make decisions based on whether a request used TCP and the measured TCP round-trip time between the client and Cloudflare. These fields help you understand protocol usage across your traffic and build policies that respond to network performance. For example, you can distinguish TCP from QUIC traffic or route high latency requests to alternative origins when needed.
Field Type Description cf.edge.client_tcpBoolean Indicates whether the request used TCP. A value of true means the client connected using TCP instead of QUIC. cf.timings.client_tcp_rtt_msecNumber Reports the smoothed TCP round-trip time between the client and Cloudflare in milliseconds. For example, a value of 20 indicates roughly twenty milliseconds of RTT. Example filter expression:
cf.edge.client_tcp && cf.timings.client_tcp_rtt_msec < 100More information can be found in the Rules language fields reference.

You can now access preview URLs directly from the build details page, making it easier to test your changes when reviewing builds in the dashboard.
What's new
- A Preview button now appears in the top-right corner of the build details page for successful builds
- Click it to instantly open the latest preview URL
- Matches the same experience you're familiar with from Pages
-
Cloudflare Access for private hostname applications can now secure traffic on all ports and protocols.
Previously, applying Zero Trust policies to private applications required the application to use HTTPS on port
443and support Server Name Indicator (SNI).This update removes that limitation. As long as the application is reachable via a Cloudflare off-ramp, you can now enforce your critical security controls — like single sign-on (SSO), MFA, device posture, and variable session lengths — to any private application. This allows you to extend Zero Trust security to services like SSH, RDP, internal databases, and other non-HTTPS applications.
For example, you can now create a self-hosted application in Access for
ssh.testapp.localrunning on port22. You can then build a policy that only allows engineers in your organization to connect after they pass an SSO/MFA check and are using a corporate device.This feature is generally available across all plans.

AI Search now supports reranking for improved retrieval quality and allows you to set the system prompt directly in your API requests.
You can now enable reranking to reorder retrieved documents based on their semantic relevance to the user’s query. Reranking helps improve accuracy, especially for large or noisy datasets where vector similarity alone may not produce the optimal ordering.
You can enable and configure reranking in the dashboard or directly in your API requests:
JavaScript const answer = await env.AI.autorag("my-autorag").aiSearch({query: "How do I train a llama to deliver coffee?",model: "@cf/meta/llama-3.3-70b-instruct-fp8-fast",reranking: {enabled: true,model: "@cf/baai/bge-reranker-base"}});Previously, system prompts could only be configured in the dashboard. You can now define them directly in your API requests, giving you per-query control over behavior. For example:
JavaScript // Dynamically set query and system prompt in AI Searchasync function getAnswer(query, tone) {const systemPrompt = `You are a ${tone} assistant.`;const response = await env.AI.autorag("my-autorag").aiSearch({query: query,system_prompt: systemPrompt});return response;}// Example usageconst query = "What is Cloudflare?";const tone = "friendly";const answer = await getAnswer(query, tone);console.log(answer);Learn more about Reranking and System Prompt in AI Search.

Cloudflare CASB (Cloud Access Security Broker) now supports two new granular roles to provide more precise access control for your security teams:
- Cloudflare CASB Read: Provides read-only access to view CASB findings and dashboards. This role is ideal for security analysts, compliance auditors, or team members who need visibility without modification rights.
- Cloudflare CASB: Provides full administrative access to configure and manage all aspects of the CASB product.
These new roles help you better enforce the principle of least privilege. You can now grant specific members access to CASB security findings without assigning them broader permissions, such as the Super Administrator or Administrator roles.
To enable Data Loss Prevention (DLP), scans in CASB, account members will need the Cloudflare Zero Trust role.
You can find these new roles when inviting members or creating API tokens in the Cloudflare dashboard under Manage Account > Members.
To learn more about managing roles and permissions, refer to the Manage account members and roles documentation.

To give you precision and flexibility while creating policies to block unwanted traffic, we are introducing new, more granular application categories in the Gateway product.
We have added the following categories to provide more precise organization and allow for finer-grained policy creation, designed around how users interact with different types of applications:
- Business
- Education
- Entertainment & Events
- Food & Drink
- Health & Fitness
- Lifestyle
- Navigation
- Photography & Graphic Design
- Travel
The new categories are live now, but we are providing a transition period for existing applications to be fully remapped to these new categories.
The full remapping will be completed by January 30, 2026.
We encourage you to use this time to:
- Review the new category structure.
- Identify and adjust any existing HTTP policies that reference older categories to ensure a smooth transition.
For more information on creating HTTP policies, refer to Applications and app types.

Logpush now supports integration with Microsoft Sentinel ↗.The new Azure Sentinel Connector built on Microsoft’s Codeless Connector Framework (CCF), is now avaialble. This solution replaces the previous Azure Functions-based connector, offering significant improvements in security, data control, and ease of use for customers. Logpush customers can send logs to Azure Blob Storage and configure this new Sentinel Connector to ingest those logs directly into Microsoft Sentinel.
This upgrade significantly streamlines log ingestion, improves security, and provides greater control:
- Simplified Implementation: Easier for engineering teams to set up and maintain.
- Cost Control: New support for Data Collection Rules (DCRs) allows you to filter and transform logs at ingestion time, offering potential cost savings.
- Enhanced Security: CCF provides a higher level of security compared to the older Azure Functions connector.
- ata Lake Integration: Includes native integration with Data Lake.
Find the new solution here ↗ and refer to the Cloudflare's developer documention ↗for more information on the connector, including setup steps, supported logs and Microsfot's resources.

Radar now introduces Top-Level Domain (TLD) insights, providing visibility into popularity based on the DNS magnitude metric, detailed TLD information including its type, manager, DNSSEC support, RDAP support, and WHOIS data, and trends such as DNS query volume and geographic distribution observed by the 1.1.1.1 DNS resolver.
The following dimensions were added to the Radar DNS API, specifically, to the
/dns/summary/{dimension}and/dns/timeseries_groups/{dimension}endpoints:tld: Top-level domain extracted from DNS queries; can also be used as a filter.tld_dns_magnitude: Top-level domain ranking by DNS magnitude.
And the following endpoints were added:
/tlds- Lists all TLDs./tlds/{tld}- Retrieves information about a specific TLD.
Learn more about the new Radar DNS insights in our blog post ↗, and check out the new Radar page ↗.
-
The Requests for Information (RFI) dashboard now shows users the number of tokens used by each submitted RFI to better understand usage of tokens and how they relate to each request submitted.
What’s new:
- Users can now see the number of tokens used for a submitted request for information.
- Users can see the remaining tokens allocated to their account for the quarter.
- Users can only select the Routine priority for the
Strategic Threat Researchrequest type.
Cloudforce One subscribers can try it now in Application Security > Threat Intelligence > Requests for Information ↗.

Previously, if you wanted to develop or deploy a worker with attached resources, you'd have to first manually create the desired resources. Now, if your Wrangler configuration file includes a KV namespace, D1 database, or R2 bucket that does not yet exist on your account, you can develop locally and deploy your application seamlessly, without having to run additional commands.
Automatic provisioning is launching as an open beta, and we'd love to hear your feedback to help us make improvements! It currently works for KV, R2, and D1 bindings. You can disable the feature using the
--no-x-provisionflag.To use this feature, update to wrangler@4.45.0 and add bindings to your config file without resource IDs e.g.:
{"kv_namespaces": [{ "binding": "MY_KV" }],"d1_databases": [{ "binding": "MY_DB" }],"r2_buckets": [{ "binding": "MY_R2" }],}wrangler devwill then automatically create these resources for you locally, and on your next run ofwrangler deploy, Wrangler will call the Cloudflare API to create the requested resources and link them to your Worker.Though resource IDs will be automatically written back to your Wrangler config file after resource creation, resources will stay linked across future deploys even without adding the resource IDs to the config file. This is especially useful for shared templates, which now no longer need to include account-specific resource IDs when adding a binding.

AI Crawl Control now includes a Robots.txt tab that provides insights into how AI crawlers interact with your
robots.txtfiles.The Robots.txt tab allows you to:
- Monitor the health status of
robots.txtfiles across all your hostnames, including HTTP status codes, and identify hostnames that need arobots.txtfile. - Track the total number of requests to each
robots.txtfile, with breakdowns of successful versus unsuccessful requests. - Check whether your
robots.txtfiles contain Content Signals ↗ directives for AI training, search, and AI input. - Identify crawlers that request paths explicitly disallowed by your
robots.txtdirectives, including the crawler name, operator, violated path, specific directive, and violation count. - Filter
robots.txtrequest data by crawler, operator, category, and custom time ranges.
When you identify non-compliant crawlers, you can:
- Block the crawler in the Crawlers tab
- Create custom WAF rules for path-specific security
- Use Redirect Rules to guide crawlers to appropriate areas of your site
To get started, go to AI Crawl Control > Robots.txt in the Cloudflare dashboard. Learn more in the Track robots.txt documentation.

Admins can now create scheduled DNS policies directly from the Zero Trust dashboard, without using the API. You can configure policies to be active during specific, recurring times, such as blocking social media during business hours or gaming sites on school nights.
- Preset Schedules: Use built-in templates for common scenarios like Business Hours, School Days, Weekends, and more.
- Custom Schedules: Define your own schedule with specific days and up to three non-overlapping time ranges per day.
- Timezone Control: Choose to enforce a schedule in a specific timezone (for example, US Eastern) or based on the local time of each user.
- Combined with Duration: Policies can have both a schedule and a duration. If both are set, the duration's expiration takes precedence.
You can see the flow in the demo GIF:
This update makes time-based DNS policies accessible to all Gateway customers, removing the technical barrier of the API.
-
