We have contacted Network Solutions and verified that cpan.org is in the right hands and secured.
Verisign has restored the proper nameservers (*.bitnames.com) for perl.com. You should see addresses in 151.101/16. If you still see something different, please leave a comment in GitHub issue #313. Some providers or services may have sinkholed or blocked Perl.com; if you are still seeing that, please let us know.
Network Solutions has recovered the domain and your whois output should reflect that. If you notice that your firewalls or other security layers still mark perl.com as compromised, please leave us a note at https://github.com/tpf/perldotcom/issues/313.
