Sky was atrocious for us – relatively rural location so on their ‘connect’ service or whatever it was called. Utterly useless; traffic was ‘shaped’ to the nth degree – this effectively made iPlayer / 4od unusable between the hours of about 10am and 11pm. I also work from home some days and they throttle ssh connections to about 2kbps, presumably on the assumption that if you’re doing something encrypted then it must be illegal downloading. I could get around this by using a VPN but their general shaping in peak times again made any sort of connection to work impossible for about 8 hours of the working day.
Wouldn’t touch them again if you paid me. Their technical ‘support’ seemed to consist of people reading from scripts that they weren’t allowed to deviate from. Trying to speak to someone with a modicum of IT networking knowledge was impossible and incredibly frustrating.
My parents live near their exchange in a supposedly decent area and whilst I’m not sure what bundle they’re on, again we can’t Skype chat with them / they can’t use iplayer etc in peak times which is irritating in the extreme – again apparently due to shaping…
Not cheap but I’d recommend either Zen who I’ve used before, or Namesco, who I’m using currently. I pay extra for better contention ratios etc and a 60GB limit and it’s worth every penny.
