weird...
firstly your tracert is messed up... that is saying that nothing is allowing any ICMP (ping requests) on the whole route.
the second is showing that the route is ok within the academic janet network but nothing more the traceroute does not reach the outside world so i cant see what that proves other than the page loads ok
i tried to trace nwolb.com and got out of the ntl network and there appears to be a router or nwolb that does not allow ICMP...
