Strictly speaking, not all global redirects are to GOV.UK - a couple of DFE sites have a global redirect to http://www.education.gov.uk/childrenandyoungpeople/families/fostercare/fostercarestand/a00205961/closure-online-systems which then redirects to the National Archives...

Quite a few of the directgov and businesslink microsites also redirect to non-GOV.UK pages, although we don't have them represented accurately in our database at the moment and aren't planning to migrate them to Bouncer/Transition for a little while yet.
