Car Hits Utility Pole, Takes Out EC2 Datacenter

“An Amazon cloud computing data center lost power Tuesday when a vehicle struck a nearby utility pole. When utility power was lost, a transfer switch in the data center failed to properly manage the shift to backup power. Amazon said a “small number” of EC2 customers lost service for about an hour, but the downtime followed three power outages last week at data centers supporting EC2 customers. Tuesday’s incident is reminiscent of a 2007 outage at a Dallas data center when a truck crash took out a power transformer.”
