Thanks for getting this sorted!
I don't know 100% the outage is the reason, but it looks like TOTP-based multifactor authentication is not working at this point. My code didn't work to log in, though fortunately the backup codes did. Removing and trying to re-add MFA also did not work, I got an error about the code being invalid during setup, which leads me to believe there might be a clock out of sync somewhere and the TOTP code generated by my application doesn't match what the server's version is. Could be something else, of course, depending on the setup.
Fortunately passkeys do work, so I can still keep a secondary factor enabled, but perhaps worth sorting the code MFA out (or removing it).
