Probably
i guess its getting to the point where alot of people start phoning in, from what i understand from other posts, this problem has been around for about a week, im guessing most people will hold off on the phone calls for a while in the hopes that it will sort itself out, can be like that at times where you have a problem one day and the next its gone.
Anyways with a major small minority of NTL customers who frequent this forum making a big issue about it (and rightly so) i guess many many more will be calling/contacting NTL about these issues which put pressure on NTL to get it resolved.
Still running more tests, im getting max speed from London but half that from Derby, strange cos your test doesnt show that much difference.
