David,
How come others get on the site and not us? It makes sense that my 
lookup are timed out if I need a response from an authority but can't 
my name server just accept the records from a non-authoritive 
source?

I get 2 NS, neither of which respond. They are either down or named 
isn't running. When I checked yesterday I red the records wouldn't 
expire for 5 weeks...it could be a while before they bring up the NS 
again.

Dp.
