GitHub Copilot: Incident with Webhooks

Timeline of updates

1. resolved2025-01-09 02:27 UTC

   On January 9, 2025, between 01:26 UTC and 01:56 UTC GitHub experienced widespread disruption to many services, with users receiving 500 responses when trying to access various functionality. This was due to a deployment which introduced a query that saturated a primary database server. On average, the error rate was 6% and peaked at 6.85% of update requests. We mitigated the incident by identifying the source of the problematic query and rolling back the deployment. We are investigating methods to detect problematic queries prior to deployment to prevent, and to reduce our time to detection and mitigation of issues like this one in the future.
