Ping's and tracert's have very little in common with web browsing.
Web browsing uses a protocol called HTTP which is then transmitted using an IP protocol called TCP, this in turn uses a concept of "ports" and HTTP uses TCP Port 80. NTL's routers re-direct tcp80 to their proxy servers.
Ping and tracert use another IP protocol called ICMP - this does not have the concept of ports, nor is it intercepted by NTL - however it is often blocked by far end servers (hence timeouts).
Routers that respond to ping requests often only do so when they have nothing better to do - so they are not reliable measure of how well they are performing.
Maybe I should post a simple networking explanation as well - I'll see if I have time tonight.
