Microsoft Stock Down as Outage Impacts Azure Services, Grounds Flights
Late on Thursday, Microsoft Corporation experienced an outage in its Office365 and Azure services which resulted in at least two U.S. airlines grounding multiple flights, while services were still suspended early on Friday.
In pre-market trade Friday Microsoft stock dropped 1.8%.
According to Frontier Airlines, its systems were gradually normalizing early on Friday and it had started to resume flights, after its systems were affected by what it called a Microsoft outage which also affected other companies.
Frontier as well as Sun Country Airlines had grounded several flights, although the latter said an “information vendor” had experienced a global outage.
Late on Thursday Microsoft reported its Azure cloud computing platform was down, and that it was attempting to restore service.
The company’s website said the Azure outage was due to a configuration change in Azure backend workloads which led to interruption between storage and compute resources. This led to in connectivity failures that affected some downstream Microsoft 365 services.
Although Microsoft said mitigation efforts with the Azure service had been completed, it did not clarify whether the service had gone back online.
Microsoft’s service health status website showed its 365 service was experiencing “degradation,” and that users were not able to access various Microsoft 365 services and apps.
