Re: ntl peering capacity is it been upgraded?

ok regarding different external routes been used for different ntl area's this caught my attention. A ntl user was complaing of problem with his WoW connection and posted the following traceroute.

If I am right he is in reading near london.

I decided to trace the same ip and got the following.

Ok so different route, so I thought maybe they rerouted it after he managed to get thru to tier2 support so for good measure I traced a opentransit hop to see what route I got to it and to see if problematic.

Appears no problem, can someone in the south of england trace us.logon.worldofwarcraft.com please that was the target he traced so can see if the routing is indeed different, this could explain the hige differences in performances different areas appear to have.
