Here is mine for Surrey near Guildford. During this problem my speeds were down to below 2Mbits on download but near normal on upload. I spoke to technical support and after half an hour of testing with P.C. access, I have a technician booked for Friday (tomorrow). It will no doubt be a waste of time for all concerned but with luck he\she will escalate. It definitely is not TBB as my infinity connection hasn't missed a beat.
