A network issue caused the mega outage to Microsoft services like Teams, Xbox Live, Outlook and Microsoft 365 suite as millions of users worldwide including in India were left in the lurch. The company will now submit a detailed review of exactly what happened this week.
The company confirmed that it has rolled back a network change that we believe is causing an impact. Microsoft’s services were back online after more than four hours of downtime.
“We determined that a change in the Microsoft Wide Area Network (WAN) impacted connectivity between customers on the Internet to Azure, connectivity between services within regions, and ExpressRoute connections,” the company wrote on its Azure cloud services website.
The tech giant said it will follow up with a preliminary Post Incident Review (PIR) within three days, which will address the initial cause and points of repair.
“We will follow that up 14 days later with a final PIR where we will share a deep dive into the incident,” Microsoft said.
The company said it will continue to monitor recovery across the service and some customers are reporting mitigation.
“We are also connecting the service to additional infrastructure to speed up the recovery process,” it added.
Microsoft’s Teams, Outlook and some other services went down in some parts of India on Wednesday as users reported experiencing various issues.
According to Down Detector, more than 63 percent of users reported issues with the app, 26 percent with the server connection, and 11 percent with the website. The cities affected by the outage included Delhi, Mumbai, Hyderabad, Bengaluru and Chennai.
