Broken login [resolved]

There is an issue which causes a 404 error (Page not found) to be displayed after login. We're working on a fix, which should be ready shortly.

The issue affects only log-in of certain users on the UI. Jobs running inside projects are unaffected.

Update 13:01 UTC: The problem is fixed. We apologize for the inconvenience, we'll share more details in a post-mortem.
