I'm testing post codes but nothing is showing up yet. I don't really expect to see anything but hope springs eternal. I lived on the high street a couple of years ago - ADSL is near perfect there so I wish they'd started further out! The cable quality or maybe routing in Bangor's outskirts is really awful so fibre is a real boost. My parents are nearly the same distance from their exchange in a different town: they get 15+ and I get 4mbit/s!
Choose very, very carefully if you are thinking of moving from Zen.
I've been with Zen since 2005 and the support has been impeccable, though yes several times the cost of bandwidth has been an issue. My parent's connection remains on Zen.
I switched my connection to Sky for LLU and now spend 4 months in 12 seriously regretting it. There is zero
support. I'll be switching back to Zen for fibre. (this years Sky problems)
