Traffic redirection has been completed, and we’ve shifted traffic to the closest available region. Performance should now be returning to normal, if it hasn’t stabilized already. We will continue to monitor closely to ensure stability.

This incident is now resolved. We have now shifted traffic back to the NYC region. This issue was identified to be caused by a routing problem at an upstream Internet Exchange provider, which impacted connectivity and cascaded to our services. To minimize customer impact, we temporarily rerouted traffic to our Washington, DC region. Once the issue was confirmed to be resolved by our upstream partner, traffic was safely restored to the NYC region.

An issue was identified affecting our DoH service that may have impacted customers in the London region. This did NOT affect DNS1/DNS2 UDP/TCP/TLS/DoT services. We identified the fault on Tuesday the 25th and resolved the it by 20:00 UTC by updating all affected servers. In addition, we have improved our monitoring and automation by adding a new failsafe to avoid this from happening again in the future.

**Dashboard Login Failure - Postmortem** **Summary:** The system experienced a performance reduction that resulted in slower API response times and an unresponsive front-end dashboard. As a result, users encountered delays when interacting with the dashboard and during API calls. **Resolution:**  Our team identified the issue immediately and initiated an incident response. A hot fix addressing the root cause was developed, tested, and deployed the same day to restore normal service. **Next Steps:**  We are conducting a deeper review of how our systems interact with the database to identify opportunities for long-term optimization and to prevent similar issues in the future.

We are currently investigating an issue in the DNSFilter UI that is preventing manual customers from seeing Roaming Client.

What Happened with Domain Categorization and System Load (e.g. msn.com ) -Some well-known domains like msn.com and started showing up as “uncategorized,” and our backend systems experienced a large spike in traffic. Here’s what we know: What Happened: -Some websites like msn.com temporarily lost their category labels due to them being treated as uncategorized in the system. -Our platform automation tried to correct this but sent too many repeated requests at once, overloading internal systems. -This caused delays in restoring correct category information, so some domains stayed uncategorized longer than expected. -We’ve deployed a fix to reduce the load and are restoring normal behavior. Key Customer Impact: -Domains like msn.com appeared uncategorized because they dropped out of cache and couldn’t be reloaded reliably. -This could affect content filtering accuracy, especially for high-traffic or policy-critical domains. -No DNS resolution outages occurred, but policy behavior may have been incorrect. Fix: A fix has been implemented; however, due to caching, it may take 24–48 hours for affected domains to reflect the correct categorization. Workaround: In the meantime, you can either add the impacted domains to your allow list or temporarily allow uncategorized domains within your policy settings to avoid disruption.

This incident has been resolved.

Between hour 5 to 6 UTC today, a networking issue outside of our control was detected between our AnyCast nodes across the world and our query log eventing system. DNS Resolution and Filtering were NOT affected. The networking issue has since been resolved but as a result you might notice that on a daily basis, about 2% less query log entries than a usual weekday in our Query Log. We are working with our networking partners to ensure this does not happen again and we are putting extra safeguards in place to avoid this in the future.
