I'm on an ECI cabinet which may also be another reason they targeted this exchange and actually be in my favour here.
I also can't find it now, but I think my FTTPoD quote said I was 400m from the node. The only thing which goes against them doing here is the lack of competition from Virgin, but I do see a few MiFi connections in the area so with the chance of 5G making it even more viable, I can see why that may also make them consider it a viable area.
Plus when I had my second line fitted the engineer took to hook about half an hour to hook it up, which makes me wonder if there's an issue finding decent pairs as surely it shouldn't take that long.
A lot of speculation I know, just trying to remain optimistic as I'd definitely be in favour of going Gigabit and calling it a day (though not at current pricing, 330Mbit will do). No more wondering if the sync rate is going to drop again. I've already lost 3Mbit off my main line over the last few months, and 1Mbit off my second just this morning.
Also with climate change, I'd kinda like one less way for lightening to blow things up. Our chimney got hit once and despite being several feet away from the line the capacitive coupling blew up the modem, router and every NIC. (granted that was BNC networking days so it had a direct path across to every PC) That was mighty impressive though as it was an actual modem back then so it managed to surge from the phone line to the serial port, blew the IO chip and out the PCI NIC. Its fascinating and scary how far a surge can go, and perhaps more fascinating that my line worked so well for VDSL after that kind of abuse.
