yeah I am aware of how that works but routes can be manipulated and static routes can be used no isp can decide on the entire route but they can preference a particular isp been used in and out of their network.

eg. if bgp was really picking the routes without manipulation you would think it would pick the better route to myself and not only that pick the same route for me and ntlworld.com since we are on the same isp.

Whats interesting tho if i trace the ip before ntlworld.com it goes over the poorer route, and if i trace ntlworld.com it goes over abovenet again I can repeat this again and again. So what would make bgp pick a different route to the hop before the site?
