I've recently joined Sky but I'm finding their speeds a bit on the slow side (20-30Mb if I'm lucky) - I believe I'm still in my cooling off period so I'm looking for an alternative provider. I've been pondering Zen for a while now after hearing nothing but good things about them.
Sadly, I've also read that they either use BTW or TTB to provide their backhaul network. I've had issues with TalkTalk recently (no upload speed) which they were unable to fix which is why I left them for Sky - If I was to join Zen and they use TTB in my area, am I likely to experience the same issues I had when I was on TalkTalk directly?
