GitHub Copilot: Incident with Actions
Timeline of updates
- resolved
On November 21, 2023, at 09:50 UTC GitHub Actions jobs encountered delays due to an incident in our background job service caused by excessive rebalancing in a Kafka consumer group. After a quick mitigation, we began to see recovery on the job queues by 10:02 UTC. During this time window 100% of Actions jobs were delayed in starting for up to 11 minutes. Unfortunately, the rapid queue recovery sent a thundering herd of jobs to Actions hosted runner pools, causing a database deadlock that resulted in some hosted runner pools having increased latency when accepting new jobs. This affected only a small percentage of overall jobs, around 2%. Configuration changes led to a resolution and the system was fully recovered by 11:27 UTC and all in progress jobs were processed. The incident is now resolved.
