On September 29, 2025 between 16:26 UTC and 17:33 UTC the Copilot API experienced a partial degradation causing intermittent erroneous 404 responses for an average of 0.2% of GitHub MCP server requests, peaking at times around 2% of requests. The issue stemmed from an upgrade of an internal dependency which exposed a misconfiguration in the service. We resolved the incident by rolling back the upgrade to address the misconfiguration. We fixed the configuration issue and will improve documentation and rollout process to prevent similar issues.
