Last update from GitHub
On September 28, 2026, between 19:23 UTC and 22:08 UTC the Copilot Code Review service was degraded and pull request reviews did not complete in all environments. On average, approximately 70% of requested reviews did not complete. Reviews requested during this window were not automatically retried, and users needed to re-request a review from their pull request. This was due to a change in a dependent service that stopped delivering data Copilot Code Review needs to complete a review.
