What's up with Network Solutions?

What’s up with Network Solutions? When I attempt to do a whois, I get this message:

Welcome to the NSI Registrar Whois Server.

The IP address from which you have visited the NSI Registrar WHOIS database

is contained within a list of IP addresses that may have failed to abide by

Network Solutions’ Whois policy. Failure to abide by this policy can adversely

impact our systems and servers, preventing the processing of other WHOIS

requests.

If you are trying to complete an individual Whois query, you may go directly to

the NSI Registrar’s Whois lookup, and try your inquiry again.

To use the NSI Registrar’s Whois lookup, click on or copy and paste the

following URL into your browser:

Trying to do a query from my web browser results in the same message.
