Poison Cache / Negative Cache

All,
Have some issues with global-estimates.com on our name servers...it
seems we have a bad NS record(s). I was wondering if someone could take a
look at our dns at 192.223.207.77. Try to look up
fidelity.global-estimates.com on that server and you don't get a response.
However it works on other internet DNS servers ... I think I have some bad
cache but I just want to be sure. Below are some debug dumps, if you think
it helps.
Thanks.
