It's to do with markers. When you have broadband the company puts a marker on the line to say "this is ours". For some unknown reason it takes fucking ages for this marker to be removed by one company and replaced by another. BT are fucking shit for changing details, TalkTalk are probably just as bad, the other main issue is having to have a phone line for broadband. The daft thing is parts of Aberdeen have the infrastructure for cable from the old Aberdeen/Atlantic cable, but they missed being bought out by NTL/Telewest and ended up going bust.
