Fwd: .info root servers responding in authority section, not answer section?

[Tim Maestas]

	It works once for me after a cache flush or server restart,
	but not after.  I think it is because the servers that
	declude.info is delegated to (udns1.ultradns.net, 
	udns2.ultradns.net) respond to a ns query for
	declude.info with referrals.  So the original query makes
	it through, because the delegation records come from 
	the info servers (tld1 and 2.nominum.com), but once the
	server caches this delegation to udns1 and 2 it will attempt
	to query them directly.  Getting a referral to the root servers,
	the server attempts to walk the delegation tree again, and ends
	up in a loop.  dig ns declude.info +trace shows this.
