On May 20, 2025, between 18:18 UTC and 19:53 UTC, Copilot Code Completions were degraded in the Americas. On average the error rate was 50% of requests to the service in the affected region. This was due to a misconfiguration in load distribution parameters after a scale down operation.

We mitigated the incident by addressing the misconfiguration.
