Disruption with some GitHub services

Resolved

On March 18th, 2025, between 13:35 UTC and 17:45 UTC, some users of GitHub Copilot Chat in GitHub experienced intermittent failures when reading or writing messages in a thread, resulting in a degraded experience. The error rate peaked at 3% of requests to the service. This was due to an availability incident with a database provider. Around 16:15 UTC the upstream service provider mitigated their availability incident, and service was restored in the following hour.We are working to improve our failover strategy for this database to reduce the time to mitigate similar incidents in the future.

We are seeing recovery and no new errors for the last 15mins.

We are still investigating infrastructure issues and our provider has acknowledged the issues and is working on a mitigation. Customers might still see errors when creating messages, or new threads in Copilot Chat. Retries might be successful.
