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This nameserver needs to be withdrawn and fixed before it is returned to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