High-probability causes

IDE extension not authenticated or stale session.
Temporary Copilot service degradation.
Enterprise policy/network restrictions blocking requests.

Debug order for speed

Check service status first.
Re-auth extension and restart IDE.
Test in a clean workspace and alternate network.

5-Minute Decision Matrix

Signal	Likely Meaning	Action Now
GitHub Copilot unavailable for most users	Platform incident likely	Switch critical flows to backup and communicate ETA uncertainty.
Only specific account/session affected	Auth/session issue likely	Re-authenticate once and retry in private mode.
GitHub Copilot slow but not fully down	Degraded performance	Throttle non-critical tasks and reroute priority tasks.
