He never said this was for tcn.net.  Obviously, this is not the domain. 
How do I know?  Most Root servers use a 2 day TTL.  There's no way he
could've removed a 3rd NS entry and us not still see it.

FWIW, please don't refer to whois output when troubleshooting DNS. 
Whois has *nothing* to do with the normal operation of the Internet. 
DNS works something like this (assuming no local data cache)...

Client -> Resolver -> TLD/Root NS -> Authoritative -> Resolver -> Client

Whois is an information database that provides contact/ownership
information on a domain.  The nameserver listings should NOT be taken
seriously when troubleshooting DNS issues.  I've seen MANY MANY MANY
times where the root nameservers don't sync with what Whois reports.
