On July 16, 2025, between 05:20 UTC and 08:30 UTC, the Copilot service experienced degraded availability for Claude 3.7 requests. Around 10% of Claude 3.7 requests failed during this time. The issue was caused by an upstream problem affecting our ability to serve requests.
We mitigated by rerouting capacity and monitoring recovery. We are improving detection and mitigation to reduce future impact.
