Resolved - Between April 15th, 2024 (09:45 UTC) and April 18th, 2024 (19:10 UTC), Copilot completions experienced intermittent periods of degraded service availability affecting portions of Europe and North America, impacting 3.5% of users globally at its peak. This was due to rolling Operating System level maintenance updates to Copilot infrastructure within those regions, which failed to gracefully restart as intended.

The incident was mitigated by routing traffic to other regions, and was resolved once the update was completed and normal traffic routing was restored.

We are working to resolve the root issue that prevented systems from restarting gracefully, as well as improving our coordination and monitoring around backend maintenance operations going forward to reduce time to recovery from such issues in the future.
