Sounds like something is caching negative results, either a DNS server
that the machine is using or something running on your machine (eg
nscd).

The hostname resolves fine for me:
--------
$ host wikileaks.dbpro.org.uk
wikileaks.dbpro.org.uk has address 80.68.88.120
wikileaks.dbpro.org.uk mail is handled by 20 backup.mx.bytemark.co.uk.
wikileaks.dbpro.org.uk mail is handled by 10 a.mx.wikileaks.dbpro.org.uk.
$ ping -c 3 wikileaks.dbpro.org.uk
PING wikileaks.dbpro.org.uk (80.68.88.120) 56(84) bytes of data.
