the copper wire being put into the ground in 2009 is of a reduced diameter to that previously? The second table down this page shows how the distances for ADSL are substantially reduced if the copper diameter is reduced by a mere 1/10th of a mm.
Bearing in mind that it is not very long since copper was at an all-time high, could it be feasible that BT bought in a stock of thinner wire? The attentuation would not matter in an urban environment where line lengths are far shorter, but out in the sticks that higher attentuation could make a substantial difference. In fact, potentially enough to go from being a Gotspot to a Notspot.
We know that contention is a massive issue and just a single barn conversion between you and the exchange, or a new subscriber in the village, can make a noticeable difference in a broadband connection. But the copper does too, and I am pretty sure BT aren't doing another Milton Keynes and putting aluminium in - surely the lesson was learnt on that one?!
It's just a thought...Anyone from BT care to comment?!
