Microsoft 365/Office365 down (12/12/2019)

[German]A brief information for users of Microsoft 365/ The service seems to be interrupted again. And at the same time the question: Is anyone (especially in the US) affected by this malfunction?


I noticed the first message here, but also on Twitter @MSFT365Status reports that a problem has been investigated. 

Some users are not able to log in to the relevant services under Microsoft 365/Office365. Microsoft says people should use the portal, which cannot be reached due to login issues. Twitter tells me that the status reports from affected people in the USA are currently arriving on the east coast. On the Office 365 status page shows a larger peak.
