Actually, they didn't have all their DNS servers in one block.

It's also a fallacy that having DNS servers in a single block (or, 
"worse", sequentially numbered) isnecessarily a bad thing.  For a long 
while, we ran with sequentially numbered servers that were in 
completely different cities, thanks to the magic of OSPF and not using
Ethernet IP addresses as service addresses.  There are arguments for 
and against certain kinds of diversity, of course, all of which have to
do with the available failure modes.

However, in this case, both their networks are dead, and with only two
name servers, that's zero for two, and of course that /will/ be a bad
thing.

Best price is occasionally a bad sign.
