Depending on what your job is, this is either the adult equivalent of a snow day or some of the greatest stress in a long time.
I have experienced, half a decade ago during some more frequent but less lengthy O365 errors that there are some higher ups who get when this is not something you can fix and some you very much can't. Wishing strength to any "but it's our mail" and "but we bought the Claude" meetings that happen today.

The odd thing about these outages is that when they become so big that everyone is impacted then the severity almost drops, since everyone is impacted and thus just shrugs their shoulders.

Many Claude session suddenly require a re-login, which first worked but now gives
OAuth request failed
Temporarily unable to authenticate. Please retry.
Can this be fall-out from the Microsoft outage?

Is Claude on Azure? GitHub also seems affected, could seem like all of this is related to the huge Microsoft outage

Is there indication this is really a separate issue or just Claude not being able to reach Microsoft Entra for whatever periodic requests confirm the user is authenticated (and maybe this page even simply being automatic reflection that those requests are errorring frequently)?
Are people who don't use M365 experiencing issues here?

Notably this brought MCPs down, which they call Connectors on the status page. Which impacts business customers using claude to access SaaS apps, not just coders.
Reminds me of when we built Facebook apps and were at the whim of the platform.
