Incident with Copilot

Incident Report for GitHub

Resolved

On May 30th, 2024, between 03:37 PM UTC and 05:14 PM UTC Copilot chat conversations on github.com saw degraded availability, where chat requests referencing files from a repository failed. This was due to an expired security certificate, which required communication to an internal service. Overall, the error rate was 40% on average. Other Copilot chat experiences were unaffected during this time.

The incident was mitigated by rotating the certificate in question.

To prevent future incidents, we are working to reduce our time to detect and have removed certificate-based dependencies between these internal systems in the process.
