Disruption with some GitHub services
This summary is created by Generative AI and may differ from the actual content.
Overview
Disruption with some GitHub services on May 6, 2026. Between 11:02 UTC and 11:13 UTC users were unable to start or view Copilot Cloud Agent or remote sessions because requests to the session API returned errors. The outage was caused by a configuration change that removed the service’s ingress path. The change was reverted at 11:13 UTC, restoring service, and the incident remained open until 11:59 UTC for verification.
Impact
Users could not start new Copilot Cloud Agent sessions nor view existing ones for approximately 11 minutes. The impact was limited to the Copilot Cloud Agent and remote session functionality; no broader GitHub services were reported as affected.
Trigger
A configuration change to the service’s network routing inadvertently removed the ingress path required for the Copilot Cloud Agent session service.
Detection
The team became aware of the issue when users reported being unable to start or view Copilot Cloud Agent sessions and errors were observed from the session API.
Resolution
The erroneous configuration change was reverted at 11:13 UTC, which restored the session API functionality. The team then monitored the service until 11:59 UTC to confirm full recovery before closing the incident.
Root Cause
The root cause was an improper configuration change that removed the ingress path for the Copilot Cloud Agent session service, highlighting a gap in the deployment validation process.
