Policy pages for Copilot are timing out

Resolved

On January 21, between 17:50 and 20:53 UTC, around 350 enterprises and organizations experienced slower load times or timeouts when viewing Copilot policy pages. The issue was traced to performance degradation under load due to an issue in upstream database caching capability within our billing infrastructure, which increased query latency to retrieve billing and policy information from approximately 300ms to up to 1.5s.To restore service, we disabled the affected caching feature, which immediately returned performance to normal. We then addressed the issue in the caching capability and re-enabled our use of the database cache and observed continued recovery.Moving forward, we’re tightening our procedures for deploying performance optimizations, adding test coverage, and improving cross-service visibility and alerting so we can detect upstream degradations earlier and reduce impact to customers.

Investigating

We are rolling out a fix to reduce latency and timeouts on policy pages and are continuing to monitor impact.
