Leap Year isn’t just a Mexican movie with violence or Amy Adams film with love but an actual event. Apparently Microsoft’s Windows Azure cloud service did not get the memo. On February 29th, Leap Day, Azure was unable to manage their applications causing many North American users to be kicked off line. The reason for the problem was a date-related glitch in which a security certificate triggered. The Azure team did not take into consideration that every 4 years a new day ‘appears.’ To fix the problem Azure deployed a software update.

In August a power outage in Dublin caused a European cloud operator for Microsoft and Amazon to be kicked offline.
