Obviously any Sky customer would have to bring up any perceived issues with Sky themselves, it’s not really the place to discuss Sky as it’s nothing to do with BT .
FTTC ( Fibre to the cabinet ) generally uses the same headends ( OLT ) as FTTP , so it’s possible that when a new FTTP area ( PON ) is provided, any ISP that already has cable links to the OLT from their own ‘network’ ( assuming it’s not a brand new OLT , but an existing one already ‘running’ FTTC services ) could use the same cable links for their FTTC and FTTP , but obviously capacity could be compromised, if you simply add on more customers with greater bandwidth requirements , I did see some speculation on another forum that an ISP ( cannot remember which one ) currently only offers lower bandwidth packages (so not the 900Mb) because the available cable link bandwidth would be seriously compromised if all their customers , (FTTC and FTTP) were routed over it (or them, they could have several CL’s)
I don’t know , but it’s possible your friends ISP has simply routed FTTP traffic over their existing cable links and the ‘insufficient’ bandwidth available is limiting throughput, if they ‘pay’ for 900Mb , then thats the rate at which the OLT ‘talks’ to the ONT , the speed the customer experiences is nothing to do with that connection rate , so ‘speed tests’ etc , would reflect real world speeds , possibly affected by insufficient backhaul, not the connection rate.
As far as BT not offering service yet ( presumably it shouldn’t be too long before it shows on BT Consumer ) perhaps they don’t offer FTTP until the extra bandwidth necessary is available , in other words they add new cable links , rather than simply forcing all traffic along the existing backhaul, but again it’s pure speculation, the DSL checker is a BT Wholesale checker , BTw being the provider of the ‘backhaul’ for BT as well as many other ISP , some major ISP can and do use BTw in some places and third party or their own backhaul in others, you would think the DSL checker shows the BTw availability, not just BT, as BT are just one of many ISP’s that use BTw, so it could easily be that BT Consumer haven’t yet updated their own ordering systems.
