The problem is not with the "two" name servers for the domain

I was able to contact the ONE IP address and get a DNS
response. If, for some reason, you do not have a path
to that IP address, you will not get a response. And, there
is no fall-back, as both name servers are on the same IP
address
indeed and so one more running nameservices without basic competence
you have to have *two* nameservers on *different* networks to avoid
exactly this happening, be it by routing troubles, line down, machine
down or whatever and if you can't do that just use a dns provider, no
matter which one, he does it better
