Microsoft is in the final stages of “validating recovery” for users and services impacted by issues with its Azure network infrastructure on Tuesday, according to the company’s Azure status page.
Downdetector.ca shows an increase in error reports at around 7:30 a.m. ET, including issues with logins, the website and the Microsoft app. The tech company said the connectivity issues started at around 7:45 a.m. ET.
“An unexpected usage spike resulted in Azure Front Door (AFD) and Azure Content Delivery Network (CDN) components performing below acceptable thresholds, leading to intermittent errors, timeout and latency spikes,” the online advisory reads.
In a post on X, Microsoft 365 noted a “degraded performance” with several of its services and features. Two hours later, it said it “applied mitigations and rerouted user requests to provide relief.”
The advisory notes there has been an improvement in service available since 14:10 UTC (10:10 a.m. EDT), but not everything has been brought back to speed.
“As we investigate reports of specific services and regions that are still experiencing intermittent errors, we believe that our network configuration changes have successfully mitigated the impacts of the usage spike, but that these changes are causing some side effects to certain services,” the tech company wrote.
Microsoft said it has so far successfully reduced these impacts in Europe, the Asia Pacific regions and the Americas, and that “the vast majority of customers and services are fully mitigated.”
The status page for Azure still displayed a “warning” level status for Front Door users across parts of North America, Europe, Asia and Africa as of 4:20 p.m. ET, but the tech company said its efforts to restore full service are “in line with our previous estimate of recovery by 20:30 UTC,” or 4:30 p.m. ET.
Microsoft said it will provide an update on its “mitigation efforts” by 21:00 UTC, or 5 p.m. ET, “or sooner if we have progress to share.”
Earlier this month, millions of computers operating on Windows crashed after cybersecurity firm CrowdStrike released a software update. The global outage impacted 8.5 million devices, grounded several flights and left customers without access to critical services like banking and health care.
