Microsoft (MSFT) said on Wednesday that it has restored all of its cloud services after a network outage, which disrupted its Azure cloud platform along with services like Teams and Outlook that are used by millions around the world.
The Azure status page showed services affected in the Americas, Europe, Asia Pacific, and the Middle East and Africa. Only services in China and its platform for governments were unharmed.
Late in the morning, Azure said most customers should have seen services resume after a full Microsoft Wide Area Network (WAN) recovery.
An outage of Azure, which has 15 million business customers and more than 500 million active users, according to Microsoft data, could affect multiple services and create a domino effect as nearly all of the world’s largest companies use the platform.
Companies are becoming increasingly dependent on online platforms after the pandemic caused more employees to shift to working from home.
Earlier, Microsoft said that it had identified a network connectivity issue occurring with devices across Microsoft WAN. It said this affects connectivity between customers on the Internet to Azure, as well as connectivity between services in data centers.
Microsoft later tweeted that it had rolled back the network change it believed was causing the problem and was using “additional infrastructure to speed recovery”.
Microsoft did not disclose how many users were affected by the disruption, but data from the outage tracking website Downdetector showed thousands of incidents across continents.
Downdetector tracks outages by compiling status reports from various sources including users.
Microsoft’s cloud business helped boost its fiscal second-quarter earnings on Tuesday. It expects third-quarter revenue in its so-called smart cloud business to be in the range of $21.7 billion to $22 billion, despite concerns that the lucrative cloud segment for big tech companies could be hit hard as customers look to cut spending.
Azure’s cloud computing market share will rise to 30% in 2022, trailing Amazon’s AWS, BofA Global Research estimates.
Microsoft has joined other major tech companies in turning to layoffs to grapple with the weaker economy, and announced last week that it would cut more than 10,000 jobs.
Its shares fell 2.4% in pre-market trading.
Big Tech platforms outages are not uncommon as many companies ranging from Google to Meta have experienced service disruptions. Azure, the second-largest cloud service provider after Amazon, experienced service outages last year.
During the outage, users experienced problems exchanging messages, joining calls, or using any features of the Teams app. Many users have taken to Twitter to share updates about the service downtime, 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 daily operations of businesses and schools, which use the service to place calls, schedule meetings, and streamline their workflow.
There have been few signs of major disruption for the UK’s major financial services companies, as multiple messaging apps offered by service providers such as Movius and Symphony are used alongside Microsoft Teams to connect bankers to customers and office staff with their remote colleagues. .
Two sources from London, who work for two large international banks, said they did not even notice that there was a problem.
Deutsche Borse Group, which operates the Frankfurt Stock Exchange, said there was no impact on trading. Frankfurt-based Commerzbank AG (CRZBF) (CBKG) said in a statement that Microsoft is investigating several issues affecting the bank.
Other affected services include Microsoft Exchange Online, SharePoint Online and OneDrive for Business, according to the company’s status page.
