Public — what happened

Summary

GitHub Copilot reported a major disruption to its Copilot code review feature on September 4, 2026, saying that from 20:04 to 22:26 UTC a higher share of pull request reviews either never finished or never posted their comments. The company said the problem came from a change to the service's authentication permissions, which blocked it from sending some reviews to the GitHub API. GitHub Copilot said it rolled back that change and had the service working normally again by 22:26 UTC, and the incident is marked resolved.
