Aside: What with the nature of the Teams, OneDrive, etc, products being Sharepoint and Exchange in a trenchcoat this is probably creating quite a mess for services besides Exchange Online, too.
Edit: Looks like the status page needs a status page.
Status page is down. Much of our org is halted.
Fingers crossed that Azure isn't impacted (seems fine so far)
