Since sometime this morning, I’ve been seeing " Oops, unable to connect. Try reloading?" at the top of all notebooks that aren’t mine. It doesn’t seem to affect my ability to edit and / or fork though.

Edit: looks like it’s fixed!

That was my fault, @bgchen — due to a tweak to commenting. Thanks for reporting.
