GitHub uptime slips under three nines

GitHub is no longer just a code host; it is the control plane for shipping software, and that makes every outage a throughput problem, not a minor inconvenience.

• –For Enterprise Cloud customers, GitHub only promises 99.9% monthly uptime, so the platform has very little slack once teams depend on it for everything from repos to releases.
• –The February 9 incident hit Actions, pull requests, notifications, and Copilot, showing that reliability problems now spill across collaboration, automation, and AI workflows at once.
• –The Copilot policy propagation bug matters because it can block newly enabled models from surfacing, turning a service blip into a feature rollout blocker.
• –The practical response is boring but necessary: monitor GitHub like production infra and keep fallback paths for CI, repo access, and model-dependent workflows.
