You can try doing a tracert to CPAN or PPM repository too see how far it can make it out. Just keep in mind that if a firewall is dropping packets then the problem will be one hop further out than what tracert reports.
Or further. Or less far. It's not uncommon nowadays for ICMP packets to have different firewall rules than TCP/IP packets.
