AJAX errors at Bitbucket?

Lately every time I perform a website action that makes use of AJAX (such as adding a new entry to my issue tracker's Components), I get a never-ending-spinner. Refresh the page, the change is there.

Note: This is not limited to the Admin area of a project, this issue has occurred in various locations as I've used Bitbucket in the past week or so.

I would pull up Javascript Debugger in Chrome to help out, but I have enough bugs of my own to troubleshoot.

Cheers
