10 Notable Cloud Outages And What Caused Them


Amazon Web Services' Elastic Compute Cloud (EC2) cloud computing platform was struck by a power failure in a Virginia data center and quickly hit by a second power failure in the redundant system, knocking down the EC2 cloud in December 2009. The outage affected one of AWS' east coast availability zones for roughly five hours.

Before that, Amazon EC2 went down in June 2009 for an extended period due to similar power issues caused by a lightning strike.
