EU - Disruption with Copilot chat and Copilot Coding Agent

Incident Report for GitHub Enterprise Cloud - EU

Resolved

On April 22, 2026, between 15:16 UTC and 19:18 UTC, users experienced errors when interacting with Copilot Chat on github.com and Copilot Cloud Agent. During this time, users were unable to use Copilot Chat or Copilot Cloud Agent. Copilot Memory (in preview) was not available to Copilot agent sessions during this time. The issue was caused by an infrastructure configuration change that resulted in connectivity issues with our databases. The team identified the cause and restored connectivity to the database. Copilot Chat and Cloud Agent for github.com were restored by 18:16 UTC. Remaining regional deployments were restored incrementally, with full resolution at 19:18 UTC. We have taken steps to prevent similar infrastructure changes from causing these kinds of database operations in the future.
