The Attercliffe exchange is in the middle of a lot of commercial properties,very near the Don Valley stadium and the English Institute of Sport,it is also quite close to the large Meadowhall Shopping centre.
Perhaps this is one reason why they won't upgrade as the places mentioned will already be able to get quite a decent BB speed.
Where as myself live virtually at the end of the exchange catchment area.
I know already mentioned is the bigger financial outlay to reach the areas further away from exchanges,but surely this is where the money should be spent to enable those who can not get/or get very little BB speeds to catch the rest of the country up
