I'm using Xcode 13.3.1. Maybe you can install this older release?

Thank you for updating the Developer System Status! Very much appreciated! It did feel a bit isolating when it was "green" for so long, when so many of us were having issues as is clear by this thread. I look very forward to the fix!

It was working fine last night, and today... now I just get a "Error: HTTP status code: 401. Unauthenticated." error. System Status is showing everything as "resolved". I'll keep trying and see if it comes back to life again.

...and we're back!
