I live in the Birmingham area and have been having major problems for about a week - - I email ntl but no response up to now. Couldn't get on at all on Thursday or Friday, got on for 10 minutes on Saturday and about the same on Friday - - at greatly reduced speed, maybe 21 -22000 - - I'm not used to real fast speed . 40000 if I'm very lucky but mor elike 34000, so 21000 taking the prverbial methinks. This week not quite so bad, though do get a lot of 'line busy' messages and 'port diconnected, hardware failure' - -also disconnects every 5 minutes or so.
I get no such problems when using tiscali or btopenworld pay-as-you-go but hey, pay £15/month for anytime and anytime is what I want.
Just my 2 penneth
