dns

I have 1 primary DNS server (ns1.mydomain.com) running on Fedora and 2 secondary ones (ns2 and ns3). DNS changes made on my web servers first goes to the primary name server and then propagates to the secondary servers. After making a DNS change on a domain on the web server, I can't see the new dns information on my ns1 when I perform:

dig @ns1 A blahblah.com

I then went to the master records on the names server (uses named) in the directory /var/named/run-root/var/named/masters and I see the A record has been updated appropriately.

Tailing the logs /var/log/messages is not showing any errors. What could be the issue?
