Upstream

We just had some bad weather and the modem disconnected overnight.   Is that a sign of a plant issue?   Unicast errors etc etc.

Disconnected overnight?  How did you know it disconnected?  You may have had a temporary power outage...somewhere on the route...but as soon as power restored, your modem renegotiated and returned online.  The outage could have been at the plant but it could have been anywhere.

Do you have a bad connection now?

Signals have come down a bit (not going over 52).  I guess there was maintenance in the area.  Thanks for replying to me posts.   I was just concerned over power levels because last year a plant tech had to repair a hardline to an amp that was  barely connected.  It was either due to past  hurricane damage or whoever did it didn't care.  Upstream has been around 41 to 45 until recently.   I was concerned that this issue was returning because the amp isn't fastened to a pole   It's just hanging after the power company changed poles. 

Its all over the place.  From 40 up to 51 and back down again.  Not the normal 3 db variation that you would expect.

It seems to have fixed itself for now.
