I might've seen something along those lines with Azure/M365. It wasn't really an authentication bug - the servers that provided authentication were down. Like if you want to go to a website but can't resolv the hostname in DNS, it doesn't mean DNS is broken if the whole server that runs DNS is down. The server is broken.
It was more of a symptom than a cause.
Good catch on that issue though. I remember something about it Friday morning because I checked my cloud PC and it was still working.
