Yes, but if your DNS is still working, people trying to email to you have 
their mail held until you're back up (usually for four or five days).  And 
people who try to find your website get told your connection is temporarily 
down.

If your DNS is NOT still working, people who send you email and people who 
try to find you on the web are told you don't exist, that they shouldn't 
bother to try again.

Which message would you rather your customers see?

What's refresh?  And where do you set it?

My guess is you mean TTL.  Which you can set on the RaQ3, but not on the 
RaQ2 (not using the gui, anyway).  And it really doesn't matter; so many 
major nameservers have been patched to ignore it <frown>.
