Still not enough to filter out incompetent ISPs...
Switching to SSE fibre (they're a reseller of Daisy) has been a disaster for me.
Sure, I get the advertised ~38Mbps EARLY IN THE MORNING.
Evenings? Forget it, Daisy's backhaul is so hopelessly saturated I'm lucky if I get 2Mbps.
Complete waste of time - and it seems there's nothing SSE can do about it.
My own fault, I should have realised the deal was too cheap, but even if there had been postcode-level mapping available, I would still have been suckered. I'm currently arguing with them to escape from my 18-month contract, on the basis that what they're providing isn't worthy of the term "broadband" :-P
