Bogus A record somewhere

I am troubleshooting an issue with a domain "troiless.com".

The servers that are (should be?) authoritative for the domain
(ns1.zoneedit.com, and ns5.zoneedit.com) have an A record for
"sphinx.troiless.com" which points to "207.88.76.3":

[adama at cinder adama]$ dig @ns1.zoneedit.com sphinx.troiless.com

; <<>> DiG 8.3 <<>> @ns1.zoneedit.com sphinx.troiless.com
; (1 server found)
;; res options: init recurs defnam dnsrch
;; got answer:

However, when we look it up on machines that are not authoritative and don't
have anything for the troiless.com zone in cache, we get the following:

[adama at cinder adama]$ dig @ns1.secure.net sphinx.troiless.com

When I dump the database I find this line:

sphinx  91871   IN      A       64.128.119.65   ;Cr=answer [192.33.14.30]

It looks like 192.33.14.30 is the machine where this bogus data is coming
from, but even if the machine (belonging to Verisign acording to whois
reverse DNS) has bad data, why is everyone querying it?

Thanks,
