### resolved, 2026-08-27 00:26 UTC

On August 26, 2026, from 21:55 UTC to 23:58 UTC, 2.6% of workflow runs triggered by pull request events were delayed, with the impact rising as high as 25% at its peak. Some users also experienced delays in pull request merge-commit generation, mergeability information, and merge-button availability. Actions and Pull Requests fully recovered by 23:58 UTC; the incident was resolved at 00:26 UTC after normal operation was confirmed. Background jobs that process pull request updates and generate merge commits were impacted by timeouts reaching a single partition of git data. This resulted in a backlog in pull request merge-commit processing, delaying pull request-triggered GitHub Actions workflows and some mergeability information. We reduced workload, shifted traffic away from affected infrastructure, and restored the affected service component to a healthy state. Together, these actions helped drain the backlog and restore normal operations. We are working to improve resource saturation

### monitoring, 2026-08-27 00:26 UTC

The degradation affecting Actions and Pull Requests has been mitigated. We are monitoring to ensure stability.

### investigating, 2026-08-27 00:25 UTC

We confirmed full recovery beginning at 23:58 UTC. Actions workflow runs and pull request merges are operating normally. We will now resolve the incident while continuing to monitor service health.

### investigating, 2026-08-27 00:01 UTC

We've applied mitigations and are seeing recovery in Actions workflow runs and blocked pull request merges. We're continuing to monitor for sustained health of merge commit creates before resolving.

### investigating, 2026-08-26 22:57 UTC

We are investigating elevated delays and timeouts affecting Actions workflow runs triggered by pull request events. 20% of actions runs have delayed starts of more than 5 minutes and up to 4% of runs failed to trigger. We are actively working on mitigation and will provide updates as we learn more.

### investigating, 2026-08-26 22:56 UTC

We are investigating reports of degraded performance for Actions and Pull Requests
