   On September 4, 2026, between 20:04 and 22:26 UTC, GitHub Copilot code review experienced an increased failure rate. Affected pull request reviews failed to complete or post review comments.<br /><br />The incident was caused by a change to the service’s authentication permissions that prevented it from submitting affected reviews to the GitHub API. We reverted the change and restored normal operation by 22:26 UTC.<br /><br />We apologize for the disruption.
