I ordered mine at 3pm Thursday. By 9am Friday it was working (hadn't checked until then so maybe earlier).

I was quoted 62/17 or something by sky, and BT Inifity checker (postcode only as not got a BT line) said 63/20. I actually end up syncing at 80/20 and I get solid 8000kbps and 2000kpbs odd up speeds so all in all very happy with the service. Love it.
