Microsoft Corp has been hit by a network outage that has taken its cloud platform Azure and services like Teams and Outlook offline, potentially affecting millions of users worldwide.
Azure’s status page showed that services were affected in the Americas, Europe, Asia Pacific, Middle East, and Africa on Wednesday.
Only services in China and its platform for governments were not affected.
A failure of Microsoft’s Azure cloud computing platform could impact a variety of services and create a domino effect as nearly all of the world’s largest companies use the platform.
“We have determined that the network connectivity issue occurs with devices on the Microsoft Wide Area Network (WAN),” Microsoft said.
This impacts connectivity between customers on the Internet and Azure, as well as connectivity between services in data centers.
Microsoft added in a tweet that it had reverted a network change it believed was causing the problem.
“We will monitor the service as the rollback takes effect,” it said.
Microsoft did not disclose how many users were affected by the outage, but data from the outage tracking website Downdetector showed thousands of incidents across continents.
The Downdetector site tracks outages by collecting status reports from sources, including user-submitted errors on its platform.
Outages of Big Tech platforms are not uncommon as several companies ranging from Google to Meta have seen service outages. Azure, the second largest provider of cloud services after Amazon, experienced outages last year.
However, with an increased reliance on online platforms as more employees have worked from home over the past three years, any outage has a greater impact.
During the outage, users experienced problems exchanging messages, participating in conversations, or using features of the Teams application. Many users took to Twitter to share updates about the service disruption, with #MicrosoftTeams trending as a hashtag on the social media site.
Used by more than 280 million people worldwide, Microsoft Teams is an integral part of the day-to-day operations of businesses and schools, who use the service to make calls, schedule meetings and organize their workflow.
Among the other affected services were Microsoft Exchange Online, SharePoint Online, OneDrive for Business, according to the company’s status page.
