The Wikimedia Foundation domain name portfolio has been transferred from GoDaddy to MarkMonitor. The portfolio transfer was fully completed yesterday. The transfers were done with any interruption of service during the procedure.
Wikipedia is the 5th most visited website in the world and the Wikimedia Foundation cares about who handles their domain names. The legal department at Wikimedia felt that GoDaddy was not best fit for their domain names. GoDaddy initially supported the Stop Online Piracy Act (SOPA), which was a controversial anti-piracy legislation in the U.S. House of Representatives.
Wikimedia said that they were very impressed with MarkMonitor. Wikimedia has been looking to switch from GoDaddy this past December. MarkMonitor is a U.S. based registrar with an office in San Francisco and is experienced with managing high-traffic domains.
