I'm getting a pretty rapid response from their web pages (< 5 seconds 
for their database lookups using host names). Since we're using the same

Curious. They've done it for mine without fuss or bother.

They also run the DNS servers for my domain; I don't know if that makes 
any difference anywhere.
