GitHub experienced a significant service disruption affecting Copilot, Actions, and multiple core services. The incident began around 7:00 PM UTC on March 3, 2026, with reports of degraded availability across Git Operations, Webhooks, API Requests, Issues, Pull Requests, Codespaces, and Actions.

By 7:17 PM UTC, GitHub engineers identified the root cause and applied a mitigation, reporting service recovery across most affected systems. Copilot and Pull Requests were among the first services to return to normal operation by 7:31 PM UTC. The company stated that impact was "mostly isolated to git operations" as recovery progressed.

GitHub's status page showed a rapid sequence of updates as services were restored individually. The incident highlights the interconnected nature of modern development platforms and the cascading effects when core infrastructure experiences problems. While most services returned to normal within 30 minutes, the brief outage underscores the critical dependency developers have on cloud-based development tools.
