Re: more peering stuff, whats going on.

Ok I will address the savvis bit first. You will see one of the traceroutes to myself I pasted is not over savvis at all that one was from justedge it hit tiscali, which it then used all the way to ntlworld.com but to me it went to level3 then to me taking a longer route.

sagonet which I didnt paste is just level3 all the way.

the trace to you from lt is as I expected over opentransit, every single ntl ip I have tested except me and one other guy uses opentransit. Also it is only 120ms to your ubr so I think your problems are on of the 3.

1 - your ubr is causing an extra 80ms lag (very over subscribed) but this isnt likely I think.
2 - your LT switch is faulty or saturated try asking to be moved.
3 - your LT server has a problem.

I think number 2 is most likely since you say everyone has the problem, whilst in my case only 2 of us out of about 20 people I have had testing have problems. I also get on non savvis routes.

Here is the trace to you excluding last hop of course.

I find it very odd that every ip I trace on ntl uses what appears to be bgp but I am routed over level3 or cogent everytime.
