Comparison site Broadband.co.uk has released its latest anecdotal monthly broadband speed testing results for March 2010. It shows that the average UK download speed for the largest ten ISPs has fallen slightly from 4.659Mbps in February 2010 to 4.527Mbps now.

As per usual Virgin Media UK continues to dominate the download speed chart with an impressive score of 8.192Mbps, thanks in no small part to its increasingly fast cable ( DOCSIS3 ) based network. Virgin is, as usual, followed by O2 ( Be Broadband ) on a respectable score of 5.355Mbps. The rest of the pack continues to fall somewhat short of both.
