Microsoft 365 gestört (13. Februar 2020)

[English]Kurzer Wink vorm Feierabend: Wenn es mit der Microsoft Cloud ruckelt, liegt es nicht an eurem Internetkabel. Microsoft hat eine Störung auf Microsoft 365 in seiner Cloud gemeldet. Ergänzung: Es scheint Zertifikatsprobleme zu geben.

Ich bin mal wieder nichts ahnend so auf Twitter unterwegs, als mir dieser Tweet vor die Füße plumpste.

We've identified a portion of infrastructure responsible for processing Microsoft 365 access requests was experiencing issues. We've rerouted traffic to alternate systems to mitigate impact. Additional information can be found under MO203839. ^RC
