qas that packetloss I have seen on just about every BT graph posted in public, it appeared on my own graphs within a week of the policy change.
Its also on gateway graphs, eg. its on your gateway graph and its on my gateway graph which rules out local connection issues.
Here is my gateway.
I dont really notice major issues during that time, speeds are shaky hovering maybe in 60-100% range but nothing breaks, websites remain snappy, ssh terminals all fine etc. In short if I didnt have the tbb graph I wouldnt have any symptons of packetloss.
But regardless it is on the graph and has been since the start of feb 2013.
Speed right now is full speed and actually any speedtests I have done in the past week have been full speed, so I think that packetloss is having no correlation with my experience.
