CIO: On Tuesday, some customers of Microsoft's Azure cloud computing service experienced outages . Those in the south-central U.S. region fared the worst. According to a Microsoft blog, "Windows Azure operations became aware of an issue impacting the compute service in a number of regions. The issue was quickly triaged, and it was determined to be caused by a software bug. While final root cause analysis is in progress, this issue appears to be due to a time calculation that was incorrect for the leap year."
Businesses that use the Azure cloud expressed frustration about the outage. "I think we could have lost 2 prospects who are testing our system currently," one customer wrote in a forum. "But I can't imagine the damage this has done to companies with large scale customers. I mean we have chosen Windows Azure due to the redundancy..... How can we explain this to our customers."
Microsoft reported that most Azure services had returned to normal by early Wednesday morning.
