Microsoft customers on its cloud platform Azure along with services such as Teams and Outlook faced significant issues.
Azure’s status page showed services were impacted in Americas, Europe, Asia Pacific, Middle East and Africa. Services in China and its platform for governments were not hit, Reuters news report said.
An outage of Microsoft’s cloud computing platform Azure can impact a variety of services and create a domino effect as almost all of the world’s largest companies use the platform.
“We’ve determined the network connectivity issue is occurring with devices across the Microsoft Wide Area Network (WAN),” Microsoft said. This impacts connectivity between clients on the internet to Azure, as well as connectivity between services in datacenters.
Microsoft in a tweet said it had rolled back a network change that it believed was causing the issue. “We’re monitoring the service as the rollback takes effect.”
“We have identified a recent change to WAN as the underlying cause, and have taken steps to roll back this change. Our telemetry shows consistent signs of recovery from 09:00 UTC onwards across multiple regions and services, and we are continuing to actively monitor the situation. With WAN networking now seeing recovery, we are working to ensure full recovery for impacted services,” Azure said in its status page.
Starting at 07:05 UTC on 25 January 2023, customers experience issues with networking connectivity, manifesting as network latency and/or timeouts when attempting to connect to Azure resources in Public Azure regions, as well as other Microsoft services including M365, PowerBI.
“We’ve determined the network connectivity issue is occurring with devices across the Microsoft Wide Area Network (WAN). This impacts connectivity between clients on the internet to Azure, as well as connectivity between services in datacenters, as well as ExpressRoute connections. The issue is causing impact in waves, peaking approximately every 30 minutes,” Azure said in its status page.
Microsoft did not disclose the number of users affected by the disruption, but data from outage tracking website Downdetector showed thousands of incidents distributed across continents.
Microsoft Azure, the second largest cloud services provider after Amazon Web Services (AWS), faced outages last year.
During the outage, users faced problems in exchanging messages, join calls or use any features of Teams application. Users took to Twitter to share updates about the service disruption, with #MicrosoftTeams trending as a hashtag on the social media site.
Microsoft Teams, used by more than 280 million people, forms an integral part of daily operations for businesses and schools, which use the service to make calls, schedule meetings and organize their workflow.
Among the other services affected were Microsoft Exchange Online, SharePoint Online, OneDrive for Business, according to the company’s status page.
