6. resolved Mar 02, 2026, 10:04 PM UTC

   On March 2nd, 2026, between 7:10 UTC and 22:04 UTC the pull requests service was degraded. Users navigating between tabs on the pull requests dashboard were met with 404 errors or blank pages. This was due to a configuration change deployed on February 27th at 11:03 PM UTC. We mitigated the incident by reverting the change. We’re working to improve monitoring for the page to automatically detect and alert us to routing failures.
