I am having an issue and hopefully this is a reasonable place to ask it.
bind is 9.3.2
I have set up some new services for a customer on one of my servers.
They maintain their own dns elsewhere so I am not providing dns for
this domain. I gave them the IP address for their new service I host
and they added it to their dns for the domain. The new record was
for t.medialytics.com . However, I cannot access it since my own
name servers return bogus information. I am not sure at all why. I
have checked each of the gtld servers to see if there was bad info,
but that was not it. I updated my root server list just in case. I
checked all my own zones I serve to make sure there was no bogus zone
info. I flushed the cash and indeed restarted all my bind instances.
Both of my dns servers give the wrong thing. It is best illustrated
by looking at the following to dig results
There are no references to sedoparking or medialytics in any of my
zone files or configuration or anything
The first one shows the bogus info:

I have no idea where the bogus info is coming from.
My named.conf looks like
options {
directory "/etc/namedb/zones";
pid-file "/var/run/named/pid-file";
listen-on {
209.41.94.134;
};
forwarders {
198.60.22.2;
};
allow-transfer {
209.41.94.0/24;
};
};
key "rndc-key" {
algorithm hmac-md5;
secret "snipped";
};
controls {
inet 209.41.94.134 port 953
allow { 209.41.94.134; } keys { "rndc-key"; };
};
zone "." {
type hint;
file "named.root";
};
include "named.domainlist.conf";
