Near as I can tell, the network that your nameservers are in,
68.168.144.0/20 is being correctly announced by AS21560 which is
"Netstream Communications". I see this announcement here. A traceroute
goes as far as,

looks like something within Netstream or between them and Cogent.

Also both your nameservers seem to be right beside each other in the
same netblock -- that's not really the best idea for just this
sort of reason. It'd be a good idea to have secondary nameservers
somewhere else (Esgob do free secondary anycast DNS and they're nice
folk).
