Broadband.co.uk has released its latest anecdotal monthly consumer broadband ISP speed testing results for the past month of August 2011, which saw the average UK internet download speed fall back slightly from a record high of 8.313Mbps in July 2011 to 8.056Mbps now. By contrast the average upload speed was able to maintain a fairly unchanged rate of 1.209Mbps.

Cable giant Virgin Media has managed to maintain its lead as the fastest broadband ISP with an average download rate of 16.971Mbps (down slightly from 17.398Mbps in July) and stable uploads of 2.484Mbps.

Both BT and Eclipse Internet made significant gains in both upload and download performance this month. Meanwhile the once strong O2 ( Be Broadband ) appears to have lost its edge and shows no sign of a resurgence. PlusNet also lost some speed and AOL can once again be found floundering at the bottom.
