See the irc channel for more information (I have logs if you need

i cannot reach that machine from three different networks (DE, UK,

tcptraceroute stops at

8m-iptv-bb-vl92.corbina.net

which is the machine right in front of that. When trying to telnet to
port 80 on that machine, I`m getting the following:

So no answer from your side, whatsover. Are you doing some strange
ICMP rejection things somewhere in the path?
