I've just been upgraded. My area reference is 31 if that helps. When I got home from work the website said I'd been upgraded but it's taken a while to actually happen. Suddenly lost connection did a reboot of the modem and now a speed test shows 20.30Mbps download. Excellent, and that's on an old NTL 250 modem
Fast enough for me for now and means I don't need a superhub.
