   On April 14, between 00:58 UTC and 06:08 UTC, GitHub Enterprise Cloud customers experienced 500 errors when attempting to access Copilot Insights pages which was caused by an authentication failure in our metrics pipeline. We fully mitigated the issue and validated the fix in production. Approximately 709 users were impacted. The total impact duration was approximately 5 hours and 10 minutes. Our investigation determined the incident was caused by a change in a tenant credential which caused authentication errors to retrieve the required data needed on our Copilot Insights pages. We understand this disruption impacted customers' ability to access the Copilot Insights page. To prevent similar issues and reduce resolution time in the future, we are investing in improved diagnostics tooling to quickly identify the root cause of failures, enhanced monitoring, and alerting to detect issues at a more granular level. GitHub is a critical infrastructure for your work, your teams, and your businesses. We are focused on these remediations and continued reliability improvements for Copilot Insights and related metrics experiences.
