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This nameserver needs to be withdrawn and fixed before it is returned to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

    194.0.1.36        ns36.cdns.net
