	Broken delegations.  Take the example below.  There are
	only glue records for the nameservers and not the actual
	records themselves.

	What is past to the parent is supposed to be a *copy* of
	what is in the child zone.  The applies equally to NS, A
	and AAAA records.  Zone administators fail to do this.

	Note most of these error could be caught at registration
	time except people seem to want "fast" over "correct".

> Do I have to modify my DNS server timeout?

	No.
