I lived on Dartmoor last year. I can testify that the broadband rollout stopped. We managed to get 5mb which wasn't so bad, the real problem was the connection would drop 2/3 times an hour. Fine for casual use but terrible for remote work.

The house we stayed in is now in the starlink queue.

We're stuck on 18/1mbs up in the rural north (and that's with AAISP, so we're getting the most the line can provide), B4RN (Broadband for the Rural North - which would have been 1gbs fibre) has stalled because of Politics.

I've just stuck an external antenna up and we're getting a decent 4G signal from EE so that will have to do for the time being. It's peaking at 50mbs with a bit higher latency, but the upload is 25x faster than the landline which does make for far more responsive usage.

Annoyingly, there's a full Fibrus fibre rollout about 10 miles south, but apparently there's no money in running a line up the main trunk road between the two major population centres for this area.

AAISP will also do line bonding, but you’ll obviously be paying more and I’d imagine it’s not going to be that much better.

I switched over to their FTTP offering recently and, while it’s not super fast compared to what others are claiming, having a router with a weird intermittent hardware issue reminded me of how good it is to be able to immediately jump on a call with technical people who actually care.
