www.northwood.mod.uk - disappeared from directory

My site www.northwood.mod.uk was listed last week in
http://dmoz.org/Regional/Europe/United_Kingdom/Government/Defence/Ministry_of_Defence/
The bottom of this page then said "Last Updated June 17th"
My listing has now disappeared and the page has now reverted to "Last Update Jan 22nd".

What has happened please ?
