Resolved
On April 16, 2025 between 3:22:36 PM UTC and 5:26:55 PM UTC the Pull Request service was degraded. On average, 0.7% of page views were affected. This primarily affected logged-out users, but some logged-in users were affected as well.
This was due to an error in how certain Pull Request timeline events were rendered, and we resolved the incident by updating the timeline event code.
We are enhancing test coverage to include additional scenarios and piloting new tools to prevent similar incidents in the future.
