Has to be the most frustrating thing about choosing to move out of town.
My village has been hooked up to 'South Yorkshire Digital Region', however the company made the decision in 2009 not to hook up one cabinet. This cabinet was on a brand new housing estate and as there weren't many people using it they skipped it. 3 years later, the estate is finished and there are over 100 hours on the thing (including mine).
Every single house in the surrounding area bar this new estate are covered, but I have to make do with 'national broadband'.
Am getting about 5Mb, which isn't bad, but it's a pain in the arse when you know how much greener the grass is across the road!
