On April 5, 2024, between 8:11 and 8:58 UTC a number of GitHub services were degraded, returning error responses. Web request error rate peaked at 6%, API request error rate peaked at 10%. Actions had 103,660 workflow runs fail to start.
A database load balancer change caused connection failures in one of our three data centers to various critical database clusters. The incident was mitigated once that change was rolled back.
We have updated our deployment pipeline to better detect this problem in earlier stages of rollout to reduce impact to end users.
