Microsoft resolves issues that led to productivity apps outage
Published 5 April 2021
Microsoft has said that it has successfully resolved the issues that led to an outage which affected cloud services on April 1.
The affected services included Azure, Teams and Dynamics 365, according to reports. “We’ve successfully resolved the issue that was causing residual impact for SharePoint Online and we’ve confirmed that all Microsoft 365 services have returned to a healthy state.” Microsoft said in a Tweet.
Spike in DNS traffic
During the outage, some users experienced “intermittent issues” with accessing Azure, Dynamics, Xbox Live and other cloud services, the Redmond-based giant said. In order to mitigate the impact of the issues, Microsoft “engaged resilient DNS capabilities to absorb the spike in DNS traffic,” the company said.
The issues on Thursday followed Microsoft’s March 15 outage that had impacted “any service” that uses Azure Active Directory, Microsoft’s widely used identity authentication solution.
During that outage, Microsoft indicated that the biggest impact was on Teams, which is used by businesses and is part of Microsoft’s Office 365 suite of productivity apps. While Asia Pacific seems to be largely excluded from this outage, Microsoft said that it has identified that a portion of infrastructure within Central United States, Western United Kingdom and France encountered errors.
Also, reports of some users in Canada, unable to send and receive Microsoft Teams chat messages were doing the rounds in the last week of March.
The outage on April 1 is the fourth such instance on Microsoft Teams since February. Teams has around 115 million daily active users worldwide as of late October, Microsoft had said in the past.
That was a more than 5 times increase from a year before, when Teams had 20 million daily active users, Microsoft said.
