What was the time difference between you the error being logged and
you testing ?

The only thing I can think of is that all their nameservers are on one
network and they have a 15M TTL. If any part of your route to their
network goes away for even a short time ... no DNS.

dig tells me (nslookup is a lousy debugging tool);

dns1.interland.net.     15M IN A        64.224.20.132
dns2.interland.net.     15M IN A        64.224.20.133
dns3.interland.net.     15M IN A        64.224.20.134


focazio.com.            15M IN MX       5 mail.focazio.com.


mail.focazio.com.       15M IN A        64.224.62.63
