Since our software update on our LNSs on Sunday we are now able to pick up the uplink speeds for DSL lines from the carrier.
However, some customers are seeing slow upload speeds and also a red line on the bottom of our monitoring graphs indicating the link is full. The problem is that BT are sending bogus uplink speeds for some lines, and therefore we are limiting the throughput.
We are working on a fix for this now.
This has now been resolved.
