Same here, though I still don't see the logic in rolling out to selected places. Surely the thought of rolling it out nationally has crossed Openreach's mind.
Interesting you mention that. Do you know if there is a vectoring trial in Cumbria? I noticed my sync speed and max attainable shoot up a week or two ago.
Yes, that increase is due to the new downstream SNR margin rollout, not vectoring. An output of the vectoring state would be required to determine if vectoring was enabled on your line.
