Re: Don't forget that some people are forced to choose fibre over ADSL
If you only got 56k from an ADSL connection you’d be entitled to a refund under Ofcom rules. Most ISPs won’t even offer a service that runs that slow.
What investment are you expecting to take place on ADSL? It’s clearly moribund. The few operators that still have ADSL kit (I think Sky, talktalk and BT) won’t be wanting to expand those footprints and the number of customers is in rapid decline (the opposite of oversubscription).
