In the post, Bill Laing, corporate VP, Server and Cloud, Microsoft, who leads the engineering organization responsible for the Windows Azure service, apologised for the outage and pointed out that a software bug had possibly triggered the glitch.
"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. The fix was successfully deployed to most of the Windows Azure sub-regions and we restored Windows Azure service availability to the majority of our customers and services by 2:57AM PST, Feb 29th," he added..
