Source code repository hosting site GitHub is currently not working. Reports about downtime began about an hour ago. The GitHub team is working on restoring the service.

“We’re continuing to investigate a significant network disruption affecting all github.com services,” the company said in an update on its status page at 5:02 p.m. Pacific.

GitHub outages don’t happen very often, although last year it faced a major distributed denial of service (DDoS) attack.

“No server is currently available to service your request,” GitHub says when you try to visit a repo. For what it’s worth, the unicorn image you see when you try to visit a GitHub website is kind of cute.
