Reading your posts, my experience of Fibre (and normal broadband before that) has been identical to yours. During the day, normal expected service. At Peak times in the evening, my fibre is slower than my boradband used to be! See my speedtest below, which is definitely not a one off. I'm in East Yorkshire though, not Glenrothes. For those that don't want to open the attached jpeg, my BT Wholesale speedtest shows 0.38Mbps download speed and describes it as "performing poorly"
