Strange delelagtion/resolving problems

[Mark.Andrews at nominum.com]

	Yes. The distance is one.
	
	What is this German habit of having nameservers not offically
	serve the zone they are in?  Is the DE registry encouraging
	this behaviour as all reported examples of this seem to invole
	German servers?
