On March 11, 2026, between 13:00 UTC and 15:23 UTC the Copilot Code Review service was degraded and experienced longer than average review times. On average, Copilot Code Review requests took 4 minutes and peaked at just under 8 minutes. This was due to hitting worker capacity limits and CPU throttling. We mitigated the incident by increasing partitions, and we are improving our resource monitoring to identify potential issues sooner.
