<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">The .COM.BS is an empty non-terminal with various child domains<br>
registered beneath. The "ns36.cdns.net" nameserver for .BS responds<br>
with NXDOMAIN to "com.bs" qname-minimised queries.<br>
<br>
This in turn can and does sometimes lead to NXDOMAIN inference for the<br>
child domains.<br>
<br>
This nameserver needs to be withdrawn and fixed before it is returned to<br>
service.<br>
