They seem to be cropping up in a lot of locations that are/were not on the list. For instance they are appearing all round Brackley even though we've never been on a G.FAST roll-out list. Nor has our [FTTC] parent exchange, Banbury. I don't actually know whether ours have anything in them or if they just the metal shell.
Some of the villages around Banbury are also having G.Fast pods installed.
A friend, living in a village a few miles north of Banbury, posted that the cabinet was humming away to itself (about 3 months ago) and, in early October, an estimated speed of 282Mbps appeared next to the G.Fast Range A entry in the Openreach checker.
Beats me why BT seem to be rolling out G.Fast to small villages (which already have FTTC) when cabinets in Banbury don't seem to be having the equipment installed and Banbury isn't even on the rollout.
I assumed someone important (from Openreach) must live in that village, as it's hard to imagine BT getting a return, on their investment, when they're concentrating on villages with fewer than 500 residents.
