Well, I'm reluctant to get my hopes too high, but according to the Scotland Superfast Broadband page, the Borthwickbrae exchange that was previously listed as "Planned" for Superfast Broadband is now saying "Coming Soon", with a date of December 2017 for the first premises to be able to receive Superfast Broadband.
This could mean that the Borthwickbrae exchange is being upgraded as part of Openreach's Gainshare program. Gainshare is the term used to describe the money pot that BT/Openreach had to set aside if the take-up of Superfast Broadband was better than expected. This is money being ploughed back into Superfast Broadband-enabling new exchanges.
PROMISING !
