It further occurs to me:

postel:~# host ns1.si-designs.co.uk
ns1.si-designs.co.uk has address 213.228.194.82
postel:~# host 213.228.194.82
Host 82.194.228.213.in-addr.arpa not found: 3(NXDOMAIN)
postel:~# host ns2.si-designs.co.uk
ns2.si-designs.co.uk has address 213.228.194.83
postel:~# host 213.228.194.83
Host 83.194.228.213.in-addr.arpa not found: 3(NXDOMAIN)

It's usually a good idea set your DNS servers to reverse resolve.  It's 
also a _very_ good idea not to have both your DNS servers on the same 
network segment.  If you want an independent secondary, drop me a line.
