GitHub hosts over 100 million repositories and is the central platform for open source development and the majority of professional software teams. When GitHub goes down, it is not just inconvenient — CI/CD pipelines stall, deployments cannot run, pull requests cannot be reviewed, and developers sit idle.
What breaks when GitHub is down
GitHub is not one service — it is a collection of services that can fail independently. Git operations (push, pull, clone) use a different infrastructure path than the web interface, which is separate from GitHub Actions, GitHub Packages, and GitHub Codespaces.
During a partial outage, it is common for git push and pull to work normally while the web interface is down, or for GitHub Actions to fail while everything else is operational. Check GitHub's status page at githubstatus.com, which breaks down status per service.
Working around a GitHub outage
The most important thing to know: your local git repository is complete. All your code, commit history, and branches exist locally and do not require GitHub to be accessible.
If you need to collaborate during a GitHub outage, you can email patches using git format-patch, share repository bundles using git bundle, or temporarily use a secondary remote. GitLab.com or Bitbucket can serve as emergency alternatives if your team needs a hosted remote.
If your deployment pipeline runs through GitHub Actions and is blocked, most teams have fallback procedures for manual deployments directly to their hosting environment.
GitHub's reliability track record
GitHub generally maintains high availability, but given the complexity of its platform, incidents occur regularly. The githubstatus.com history page shows all past incidents.
Significant outages have affected GitHub several times — most notably multi-hour disruptions affecting all services simultaneously. More common are partial degradations lasting under an hour: elevated error rates on the web interface, slow API responses, or intermittent Git operation failures.
Monitoring GitHub status
For development teams, GitHub outages warrant immediate notification. You can check WebsiteDown for live HTTP status of github.com, or subscribe to GitHub's status page for email/SMS notifications when incidents are declared.
For mission-critical workflows, consider adding GitHub status checks to your team's monitoring tooling so on-call engineers are notified automatically when GitHub experiences degradation.
