The August 6, 2026 GitHub Actions Outage: Queued Jobs, Throttled Webhooks, Impact Lasting 10 Hours
Last updated on August 12, 2026.
Introduction
On August 6, 2026, GitHub opened an incident for degraded Actions performance at 15:22 UTC. Within about twenty minutes, Actions availability was listed as degraded, workflow runs were failing to start or failing partway through, and the Actions REST API was returning errors. Pages was pulled into the same incident shortly afterwards. The status page marked Actions and Pages as mitigated at 00:05 UTC on August 7, and closed the incident at 02:04 UTC.
What the live updates showed at the time was a multi-hour recovery through constrained capacity, throttled webhooks, invalid job assignment, and self-hosted runner problems - followed by cleanup work that continued after the incident was marked resolved. GitHub added a root cause analysis to the incident page on 11 August 2026, appended to the 7 August resolve post rather than as a separate update.
