Earlier this month, Microsoft 365 users were unable to log in to multiple Microsoft 365 services that use Azure Active Directory, including Outlook, Microsoft Teams, Office.com, Power Platform and Dynamics 365. Users already logged in were unaffected and the services themselves continued to run but for most or all of the five-hour window anyone logged out was unable to log in.
Microsoft is not the only one. Adobe Creative Cloud also went down early this month. At the end of September, several Google services went offline or were barely reachable, including Google Meet, Drive, Docs, Analytics, Classroom and Calendar. In early June, IBM reported a multi-hour, multi-region cloud services disruption.
