The company also said that some of its previously impacted customers are now reporting recovery.

Microsoft observed problems In the early hours of Wednesday.

“We’ve identified a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps,” the company said.

Downdetector, a service where people can log problems and outages with websites and apps, saw a spike in users reporting issues with Microsoft products, including Outlook, Teams and the company’s cloud product Azure, at around 3 a.m. ET on Wednesday.

Microsoft said that at around 7:05 UTC — 2:05 ET — customers may “experience issues with networking connectivity, manifesting as network latency and/or timeouts when attempting to connect to Azure resources in multiple regions, as well as other Microsoft services.”

The company updated on Twitter at 9:26 GMT — 4:26 ET — that it has “rolled back a network change that we believe is causing impact. We’re monitoring the service as the rollback takes effect.”

By around 9:30 ET, Microsoft said that its services had recovered and remained stable.

The Microsoft outage comes just hours after it reported better-than-expected earnings for the October-December quarter. But the company saw a slowdown in revenue from cloud computing products, including Azure, and gave gloomy guidance for the current quarter.
