Edit: Ironically status.statuspage.io says their (own) site is operational.
Updates on Status page:
Identified - The errors are a result of some routine file system maintenance that affected our front-end machines. We are resolving the issue on each machine and will keep this page updated with our progress. We hope to have everything back in working order very shortly. 14:04 UTC
Investigating - We're experiencing slow loading times and outages for some customers loading the site pages or cloning. We're looking into it and will update once we have more information. 13:58 UTC
Though I am having issues pushing and pulling which doesn't cover cloning or the UI.
edit: so it looks like it went down between 9:30 and 10 am EST.
