This is a rather strange one. There is ~~packetloss~~ when downloading, however the download is not filling the link, but there is still loss, ~~this~~ is unusual. This turned out to be congestion on the ~~Virtual~~ ~~Path~~ within BT, or it may have been ~~miss-configured~~. It took our escalation staff 3 months to convince BT that the fault was within their network.
