nslookup fail for some places

[Morris M M Law]

An .org domain has been registered on NIC with NS1 and NS2 Domain name 
server in Hong Kong.  It was found that not all over the world in the
Internet that can resolved the .org address to IP address using nslookup.
Why?  In particular, one of the cache server B.GTLD-SERVERS.NET cannot
resolve the address.  Could anybody point out the possible cause of this
phenomena and how to solve the problem?

Thanks in advance,
