	Looks like a NS record pointing to a CNAME to me.  Note
	this could be QWEST.NET's fault as it is their server and
	they may have changed its name without informing Yale or
	following up that the change has been made.  It doesn't
	take much to grep the cached zone files to see if the old
	NS record is still there.
