Is GitHub down?

If GitHub is not working, it’s usually either because of an internal infrastructure failure on GitHub’s side or a connection failure on yours.

GitHub’s backend services are closely linked — a minor technical glitch in one can cascade across the platform. An isolated bug in user authentication can disrupt repository pushes, webhooks, or GitHub Actions. External events such as distributed cyberattacks or scheduled system maintenance can also cause intermittent downtime.

If GitHub’s servers are running normally, the issue might just be on your end. Your connection can fail due to local network misconfigurations, DNS cache issues, strict corporate firewalls, or regional ISP routing errors. In specific regions, government-level web filtering can also restrict access to GitHub. Check GitHub’s current status on this page or test your connection to determine whether the outage is global or local to your machine.

If you find GitHub Copilot not working, it might not be a general site issue — GitHub Copilot runs on a separate infrastructure, so it can fail even while github.com is fully functional.

First, check GitHub’s current status on this page to see if GitHub Copilot is down for everyone. If the status shows “Online,” check your account. Your inability to access the service could be due to an expired subscription, payment issue, or unassigned seat from your organization’s administrator.

Local setup issues are also common. These can include expired IDE authentication tokens, outdated extensions, or strict corporate firewalls blocking Copilot’s endpoints. You can usually resolve local token glitches by re-authenticating in your code editor.

GitHub Actions can suffer a service disruption separately from the main website. According to IncidentHub, Actions was GitHub’s most affected service with 57 outages (16 major) between May 2025 and April 2026.

You can check the current GitHub status on this page to clarify platform availability. Common GitHub Actions issues include slow workflows, runs stuck in “Queued” status for 10+ minutes, and unresolved “Waiting for a runner” prompts. Workflows may also start normally but time out during execution. Specific runner types like macOS, Ubuntu, or Windows might become completely unavailable, all while other GitHub services stay up.

If you’re wondering why GitHub is slow, the lag usually comes down to platform strain or local network issues.

On GitHub’s end, the growing use of AI-driven automation and agentic workflows has increased platform traffic. Similarly, heavy pages, like pull requests with thousands of code changes, take longer to render. Service-specific performance degradation can also slow response times — check the current GitHub status section above to confirm.

If GitHub is slow only for you, the bottleneck is likely your setup. Delays can arise from local network congestion, high latency due to geographic distance from GitHub’s servers, or poor ISP routing.

The GitHub message “No server is currently available to service your request” almost always means GitHub is experiencing a widespread server outage or major system failure on its end.

This error typically appears alongside GitHub’s “angry unicorn” graphic when the platform’s frontend infrastructure cannot route your request to an active backend server. A breakdown like this sits entirely on GitHub’s infrastructure — your local machine, code repository, and internet connection usually have no impact on that. Check the GitHub status and wait for its engineering team to restore server availability.

If GitHub isn’t working while there are no widely reported incidents, the issue is likely local to your setup. Here’s how you can troubleshoot to restore access to GitHub:

• Confirm that your internet connection is stable.

• Clear your browser cache and flush DNS cache to remove stale data.

• Try opening GitHub in an incognito mode window.

• Restart your router. If that doesn’t help, try a different network, such as your mobile data.
