Subject: ENT NXDOMAIN problem at .BS nameserver ns36.cdns.net

The .COM.BS is an empty non-terminal with various child domains registered 
beneath.  The "ns36.cdns.net" nameserver for .BS responds with NXDOMAIN to 
"com.bs" qname-minimised queries.

This in turn can and does sometimes lead to NXDOMAIN inference for the child 
domains.

This nameserver needs to be withdrawn and fixed before it is returned to 
service.
