Hi, for the last past 5 days every domain that I have setup the dns are not updating. When I try and do a nslookup on the domain I get messages like "** server can't find domain.com.: SERVFAI" and "** server can't find domain.com.: NXDOMAIN" Do anyone have any clue on why this is happening?

Make sure that you are completely saving your DNS entries (clicking on the Save Changes option at the bottom of the main DNS screen). If this doesn't work, try restarting your DNS server.

I have done that about a dozen times nothing happens. Its like some new sites work but others don't.
