Major disruption: Microsoft: Service completely restored

Redmond. According to Microsoft, the serious disruption to central cloud offerings from the software group Microsoft has ended. All systems were running again, the company announced on its website on Saturday morning (CET). The problems affected not only the Outlook email service, but also services from the Microsoft 365 cloud package in general.

With the office communication service Teams, for example, planning meetings and calendar connections did not work properly. In addition, the AI ​​assistant Copilot and interfaces to third-party providers were temporarily disrupted, including AI services such as OpenAI and Anthropic.

By Friday afternoon, Microsoft had already made gradual progress. The company then emphasized that the disruption was due to a domestic problem and not to a cyberattack or AI activity. There is also no connection to the technical breakdown that has led to thousands of flight cancellations in the USA since late Friday evening (CET). The reason was ultimately a previously carried out upgrade of the network capacity. A problem that was introduced only became apparent after recent network changes, it was said.
