For what it's worth, here's my Sky Fibre graph (from Cheltenham).
The blip is me flatlining it to try and make a VM style dent in the graph, no comparison really

. This is still stock with a locked Huawei modem and the not-quite-as-bad-as-the-Superhub "Sky Hub", haven't got around to putting my 'proper' hardware behind it. Very impressed.
Averaging ~11ms ping to London, awesome for gaming. VM from here was ~20ms at best due to some arse end of nowhere style routing.
