For the last couple of weeks I have been seeing signs of packet loss, there was apparently some maintenance work going on last night that I hoped would have solved it but unfortunately not. They appeared to be tinkering with upload channels as they were disappearing one by one.
My power levels appear to be in check currently.

I have a 10dB Forward Path Attenuator that was fitted after issues leading to total outage last year, I was overseas at the time and had to try and help my mum with getting VM to understand that there was an issue.
I do find that when the weather is hot like the other week, my power levels drop to -7dBmV. This also showed a lot of errors in the log and Pre and Post RS errors were in the 10's of thousands per channel. Currently there's just a few pre RS and no post RS.
When the levels were that high I took the attenuator off and that caused them to jump to +7dBmV. Now I understand that heat makes them drop but dropping from the current -3 ish to -7 is perhaps a bit drastic?
Something is quite obviously up with the network here. Noise issues? Speeds seem fine for the most part, but upload does tail off to about half from time to time.
