I thought one of the ideas of G.fast was that you've got such a large amount of bandwidth that losing a few tens of Mb isn't supposed to matter, and also it's much faster to reconnect.
They noticed the slight decrease in speeds a couple of weeks ago, they weren't too concerned about that.
Much more of concern was the amount of noticeable disconnects and amount of time where they had no sync at all which could last a few hours. There's been 157 loss of connection over the past few weeks according to the Zen RADIUS report.
What I may not have mentioned is that DLM started taking action and capped at 95Mbps.. and then I believe 24Mbps a couple of days ago which is how I interpreted the message I got which was "
Capping the speeds between 24 & 95 Mbps". So obviously one very poorly line.
The stats show the line after a DLM reset.

ETA. Just had a look at one of the other files I was sent and it would appear that the line appeared to have got worse from the 21st of July.
The more the DLM took action, it made no difference to the line stability.
