Just wondering, once you change anything to any dns record it updates the zone file? Someone was updating the zones on one of our server and he made a mistake. He fixed it a few seconds later but in the interim one of the secondary dns server polled the file and grabbed a new copy. It caused a little problem for anyone that happened to poll that dns server for a little while because it had bad data...we can purge it easy enough but it may be a good idea to let us in some future release modify the dns then submit it for changes?
