The standard FTTC options in the UK are nominally 40/10 and 80/20. I have the latter, which in reality works out as “up to 76mbit down, up to 17mbit up”. My router is currently synced at 56/11. Where G.FAST is available IIRC that is up to 250down/36up.

The engineers who invented DSL did Gbit/s speeds in the early 2000s. Unfortunately, real life 50 year old copper pairs aren't as fast as those in their lab...

Near Silicon Valley, we would get 256kbit theoretical.
