Yes:

% dig +short a dns3.potomacnetworks.com @a.gtld-servers.net
216.250.243.230

As long as that host record exists, with an IP different from what
your authoritative servers reply with, you are going to have problems,
because queries will be answered by the GTLD servers and not your own
authoritative servers.
