The old Cogent<>ntl problem is back I guess.
Permanent work is being done to sort this but will take a little while as it involves new fibre and peering connection, this should be sorted in fairly rapid time.
Also by the way that hop you said that apparently belonged to ntl doesn't it's just using an IP from an ntl range, it actually is a Cogent box
People aren't going to be getting 10Mbit or anywhere close to it a lot of the time from a lot of sites, going to be amusing people complaining like crazy about it though
Infact already sorted (for now!):
8 12 ms 11 ms 13 ms tele-ic-1-so-110-0.inet.ntl.com [62.253.185.78]
