I happened to be in Tunbridge Wells/Southborough yesterday, when I saw what looked very much like a G.Fast pod attached to one of the PCP cabinets. I wasn't 100% sure at the time if it was a G.Fast pod but now that i've compared pictures, it does indeed look like one. And indeed, checking on BT's DSLChecker on connection availability at nearby addresses, G.Fast is live!
I was very surprised to see this - i've not seen
any mention of Tunbridge Wells/Southborough getting G.Fast, nor does it appear on ThinkBroadband's Map or OpenReach's list of pilot locations!
I'm not sure how recent it is,
Google Streetview's most recent imagery from June 2017 doesn't show it however as you can see in my photo it's already started to get a bit of cobweb buildup on it. Looks to be Cabinet 50 on the Tunbridge Wells exchange.
