	www.ahwanepal.org is served by ns1.a1hosts.net and ns2.a1hosts.net
	which don't exist according to the servers for a1hosts.net. (Only
	the glue records exist).

	Similarly for the others.

	Glue records are supposed to be *copies* of records that exist.

	The A records for NS1.A1HOSTS.NET and NS2.A1HOSTS.NET need to
	be added to the A1HOSTS.NET zone.
