Lightning Strike in Dublin Downs Amazon, Microsoft Clouds

A power outage knocks out cloud computing services for many European businesses.

Computerworld: On Sunday, lightning struck a transformer in Dublin, knocking Amazon Web Services at the data center located there offline. Normally, backup generators would kick in after a power outage, but the blast also damaged those generators. As a result, many European users of Amazon's cloud computing services like EC2 (Elastic Compute Cloud) and EBS (Elastic Block Storage) were unable to access those services for many hours. At 11:04 PM PDT on Sunday evening, the company announced, "Due to the scale of the power disruption, a large number of EBS servers lost power and require manual operations before volumes can be restored ... While many volumes will be restored over the next several hours, we anticipate that it will take 24-48 hours until the process is completed."

European users of Microsoft's Business Productivity Online Standard Suite also experienced outages after the lightning strike.
