Microsoft Azure Corporate Vice President Jason Zander acknowledged the problem and explained the root cause in a November 19 blog post.Microsoft says Storage service performance update brought Azure down
On the evening (U.S. Pacific Time) on November 18, customers across the U.S., Europe and parts of Asia experienced problems with various Azure services. The issue also affected Xbox Live and MSN.com -- parts of which rely on Azure -- as well as Visual Studio Online and Search.
Further exacerbating the problem was the fact that the Service Health Dashboard and Azure Management Portal both rely on Azure Storage services, which meant those services were not accurately reflecting the impaired state of Azure storage. Many users noted that Azure's status page was reporting that Azure was working fine when it wasn't.
