I was with a small company called BRSK who did the FTTP rollout in my area, I think they have changed hands a few times now, but the sheer reliability was legit 5-9s. I don't legally fully understand how small companies ended up getting lots of money from the government for FTTP but they absolutely crushed it in my area. Shame they got mega review-bombed because they installed telegraph poles outside people's houses and that's apparently evil
