Nov 20, 2012 Failover for Frankenstorms

Hurricane Sandy inflicted devastating human losses along the East Coast. The storm also created widespread disruptions of every aspect of infrastructure in the afflicted areas—including the data centers maintained by Web hosting providers.

For example, the failure of one data center in New York City temporarily shut down commercial websites such as the Huffington Post, Buzzfeed and Gawker. To keep another data center running, its customers spent hours hauling generator fuel up several flights of stairs.

For mission-critical systems, the threat of such extreme events is one more reason to have a disaster recovery plan that includes failover to remote locations. Each server image should be deployable to multiple regions and data centers, in case there are outages in more than one area.
