tl;dr: GitHub Actions and Pages suffered a ~10 hour outage on August 6-7, 2026, causing workflow failures, delayed job starts, and impacts to Copilot code review, Copilot coding agent, and GitHub Enterprise Importer migrations. Runners were being assigned invalid jobs and webhook triggers were throttled during recovery, with some ARC runner pods stuck idle requiring manual intervention (kubectl delete or redeploy). Some push/pull request events were dropped and cannot be replayed automatically—users must re-trigger workflows manually.
