	Did you fail to update the serial?
	Did you have a old nameserver that hasn't been decomissioned?
	Was there a transient problem with one of your slaves preventing
	it updating?
	Was mail2.ceinternet.com.au ever glue for a zone?

	You delegation currently contains a mis-match.  While it won't
	cause this problem it does reduce the amount of redunancy built
	into your zone.
