QinetiQ (pronounced "kinetic") is a private corporation owned by the British government that launched the online version of the U.K. 1901 census on 2 January 2002. The site had lots of problems when it launched as tens of thousands of genealogists tried to access it at the same time. The site's servers crashed frequently and were down more than they were up in operation. You can read more about that here, here, here and here. Eventually, the company added more servers, and the load also abated. The U.K. 1901 has been stable now for more than three years.
QinetiQ is a part of DERA, the British Government's "Defence Evaluation and Research Agency." QinetiQ is a wholly government-owned corporation, according the Web site at http://www.qinetiq.com and at http://www.qinetiq.com/about_qinetiq/07history_and_ppp/index.asp.
Now QinetiQ has sold its 1901 Census online business, which it developed from scratch and operated for The National Archives, to Friends Reunited for £3.3 million. The website has played a key role in the burgeoning popularity of family tree research.
The business has been bought by Friends Reunited's genealogy website, Genes Reunited. QinetiQ will oversee the migration of the website from QinetiQ's Malvern site to Friends Reunited's head office in Oxted once appropriate systems are in place to ensure an uninterrupted service to users.
