On 17 October 2012 the Directgov website was replaced by GOV.UK.
GOV.UK does not cover every piece of content that used to be found on Directgov. The page you are looking for is probably one of these.
Essential government services and information can be found at GOV.UK.
A copy of the page you were looking for can be found in The UK Government Web Archive, however it will not be updated after 17 October 2012.
