Not everyone can do a traceroute and see results.
Many mindless ISP's and carriers block all ICMP traffic, which not only breaks traceroute and pings, but also other protocols that depends on ICMP.
Cable and DSL providers often firewall
stuff they don't need to. There are a lot of morons out there that don't know how to properly manage TCP/IP traffic. :^(
I've never been able to successfully complete a traceroute to CJ, there's a router somewhere close to them that blocks it.
