hydrofix writes "The Wikimedia Foundation is preparing for the transition its main technical operations to a new data center in Ashburn, Virginia, USA. This is intended to improve the technical performance and reliability of all Wikimedia sites, including Wikipedia. The current target windows for the migration are January 22nd, 23rd and 24th, 2013, from 17:00 to 01:00 UTC. Since 2004, Wikimedia sites have been hosted in the main data center in Tampa, Florida. In 2009, the Wikimedia Foundation’s Technical Operations team started to look for other locations with better network connectivity and more clement weather. Located in the Washington, D.C. metropolitan area, Ashburn offers faster and more reliable connectivity than Tampa, and usually fewer hurricanes."
