Microsoft (NASDAQ:) experienced an outage of Azure and Office365 services that grounded flights by at least two low-cost airlines in the United States late Thursday, with services still suspended through Friday morning.
Microsoft shares fell 1.8% in premarket trading on Friday.
Frontier Airlines said its systems were gradually returning to normal early Friday morning and that it was resuming flights, after its systems were affected by what it called a “Microsoft outage that also affected other companies.”
Frontier Airlines has grounded several flights, as has Sun Country Airlines, although the latter said one of its “information vendors” was experiencing a global power outage.
Microsoft reported an outage on its Azure cloud computing platform late Thursday, and that it is working to restore service.
A note on the company’s website indicated that the Azure outage was due to “a configuration change in a portion of the Azure back-end workloads, which caused an outage between storage and compute resources resulting in a connectivity failure that impacted Microsoft 365 services that rely on these connections.”
The company said it had completed mitigation efforts with the Azure service, but did not specify whether the service was back online.
The company’s service status site showed that 365 service is also experiencing “degradation,” and that users will not be able to access many Microsoft 365 apps and services.
Microsoft did not immediately respond to a request for comment.
