Incident with Actions
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.
Nov 21, 11:27 UTC
Update - We've applied a mitigation to fix the issues with queuing and running Actions jobs. We are seeing improvements in telemetry and are monitoring for full recovery.
Nov 21, 11:12 UTC
Update - We have recovery for the underlying issue but are waiting for Actions queues to catch up. We expect this to be completed in less than 1 hour(s).
Nov 21, 10:24 UTC
Investigating - We are investigating reports of degraded performance for Actions

We are investigating reports of degraded performance.
Resolved - On 2023-11-15, from 09:44 to 10:42 UTC, some GitHub customers experienced increased latency or errors accessing repo data.

High concurrent access to a specific git object exposed a bug that forced a backend service to perform excessive calculations, overloading the service. Access to this repo was paused while load was re-rerouted, mitigating the problem.
The conditions that triggered the expensive operations have been identified and refactored.
Nov 15, 11:34 UTC
Update - Error rates and performance have returned to normal.
Nov 15, 11:33 UTC
Update - We have identified the source of the issue and have removed the additional load from the service. Sporadic delays in pull request experiences and intermittent 500s are still occurring and impacting a very small percentage of traffic. Next update is expected within 30 minutes.
Nov 15, 11:21 UTC
Update - We are seeing connectivity issues between some of our systems and git backend services. This is causing intermittent error responses and delays in pull request experiences for a very small percentage of traffic. We are investigating mitigations and expect to provide another update within 30 minutes.
Nov 15, 11:04 UTC
Investigating - We are currently investigating this issue.
