North Yorkshire signed their BDUK agreement back in July, and have been "planning" since.
In this time, there has been ONE cabinet installed with great fanfare (there might have been a second without the fanfare, but no confirmation of this).
There has been a website created for the project (Superfast North Yorkshire
), and I imagine Norfolk will get their own. This is part of the "branding" that is being done for each county, so "they" can start to advertise locally and improve the take-up rates, without advertising any one ISP over another.
However, there has been no official announcement of the plans for any extra exchanges yet, or any infill within existing exchanges, or the result for EO lines, or the technology to be deployed for the "out-of-coverage" homes.
On the positive side... Many of the county's exchanges have appeared unofficially in Openreach's "coming soon" and "future exchanges" lists, spread evenly over 2013 and 2014. I don't have the figures to hand, but it is roughly 120 exchanges added (on top of the 18 being upgraded commercially) and at most 10 being left out.
