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).

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.

Investigating - We are currently investigating this issue.

We are investigating reports of degraded performance.

Resolved - Between 20:35 and 21:38 we experienced up to a 20 minute delay delivering around 30,000 notifications due to side effects of some planned maintenance on supporting systems. We have noted the unexpected user impact of this type of maintenance and will address it in future maintenance planning.
Nov 13, 21:38 UTC

Update - An issue related to notifications has been resolved. Users should again be seeing their notifications.
Nov 13, 21:38 UTC

Update - We're seeing issues related to notifications.

Investigating - We are currently investigating this issue.
