Another one of those moments - It just struck me when flicking through my inbox, BT is is rolling out Fibre to the Kerb across the UK, with slated speeds of 40Mbps down and upto 10Mbps up.
I had a good google around and couldn't find a clear indication of the contention ratio (down or up), or if there is QoS provision for example to offer Voice (over IP) services - interestingly the BT product includes a home hub, with internet voice, so I expect their to be QoS there.
VDSL based, so BT provide a VDSL modem with their service, and over WBC so other ISPs can wholesale provide the service.
Lets see how it works out. ... Alas I'm not on an enabled exchange - so I'm not going to find out for a while yet.
