@joss what speed are you getting with Fibre 2?
Zen quoted me for both Fibre 1 & 2 but, were still only copper around here (No BT FTTC or FTTP).
When we were with Sky, the Proliant thats in the loft sruggled especially when the rest of the house was using the net. However, at the time I was sure it was down to the 2 Sky q boxes, hence why we went back to Virgin 350 bb.
