Re: Total waste of time
I think the 500Mbps stuff is "FTTDP", the final step between FTTC (where the actual fibre stops a street away in the nearest green street cabinet) and FTTP - bringing the fibre right into the street or equivalent, at the BT DP (Distribution Point).
I get the impression BT have found the worst problems in FTTP are the final few feet, getting through people's gardens or driveways and into the home itself, so bringing fibre up through their own ducts and stopping just short makes sense for now on existing sites.
For any new-build development, FTTP makes more sense than running new copper wire - and, to be fair, Openreach seem to be facilitating this for house builders who cooperate, providing them with all the bits and information so they can pre-fibre new homes while building them - but replacing existing copper is a bigger job.
I actually have the option of 330 Mbps FTTP where I live now - for £1k or more in installation, plus a three year contract to pay about four times the price I pay now for 80 Mbps FTTC. Not really very appealing. In time, of course, regular FTTP services will be much more common thanks to new-build sites, but in the meantime I'm glad we have FTTC.
