GitHub has reported a service incident affecting Actions, Issues, Pull Requests and notifications. Investigation began at 12:21 UTC on October 12, 2026, after reports of degraded performance. Users experienced problems loading the Actions tab UI, interacting with the Checks API, queueing new Actions runs, creating and updating issues, and requesting PR reviews, including through the REST and GraphQL APIs.
By 13:02 UTC, Pull Requests were reported to be operating normally. The team applied a mitigation and monitored recovery, but an initial fix was not fully successful. At 13:38 UTC, users could still face delays and errors with Actions, Issues and Projects, and notifications remained delayed while engineers worked on the root cause.
Between 14:35 and 14:37 UTC, the degradations affecting Issues and Actions were each reported as mitigated, and monitoring continued to confirm stability. Later, at 15:19 UTC, the team mitigated the Actions, Issues and Projects problems and started work on the notification delay.
At 15:50 UTC, notifications resumed after a successful mitigation, but they remain delayed while the backlog is cleared.
