Users from 72 nations have reported outage on Microsoft Teams, Copilot, OneDrive, Azure and other services.
Several other services, including Cloud Update, Cloud Policy and Inventory, were also affected.
"While the servers we've returned to service initially remain healthy, we've observed that they can become unresponsive again once they begin receiving traffic. We're analyzing diagnostic data from these servers with our networking and platform experts to determine what's triggering this behavior," reads a statement on Microsoft services status page.
The company further added, "Building on the protective traffic management measures we've implemented, we're also temporarily limiting which types of traffic can reach the affected infrastructure in specific locations. This will help us determine whether a particular type of request is contributing to the impact and allow us to restore service incrementally."
In a post on X, the company said that the servers they returned to service can become unresponsive again once they receive traffic.
The servers we returned to service can become unresponsive again once they receive traffic; we're analyzing diagnostic data to determine what's triggering the behavior. In parallel, we're temporarily limiting which types of traffic can reach the affected infrastructure in some locations. Additionally, we're rebuilding a subset of affected servers using a previous configuration to validate if this prevents them from becoming unresponsive.

AWS services have been operating normally, however an unrelated disruption elsewhere on the internet is prompting some inaccurate news reports. The only resource on the internet that provides accurate data on the availability of our services is the #AWS Health Dashboard. We thank everyone who is confirming the facts with Amazon before publishing reports. https://t.co/nqeTHlr3mx
