Microsoft Azure, March 16
Storage availability issues plagued Microsoft's Azure public cloud for more than eight hours, mostly affecting customers in the Eastern U.S.
Some users had trouble provisioning new storage or accessing existing resources in the region. A Microsoft engineering team later identified the culprit as a storage cluster that lost power and became unavailable.
In addition to that problem, Microsoft also listed on the Azure status page a software error affecting storage provisioning across multiple services for longer than an hour.
