Domain non-existent

[Mark_Andrews at isc.org]

	The problem is that the parent domain (gov.sg) has not been
	updated.  While both pridns.gov.sg and secdns.gov.sg know about
	sgnews.gov.sg as they are also servers for sgnews.gov.sg the
	rest of the servers for gov.sg do not and hence the NXDOMAINs.

	The zone gov.sg zone needs to be updated and pushed to the
	secondaries.
