Jitter Latency and Packetloss (Intermittent)

(92691, Orange County Cox)

I sent the email below to CoxHelp but I've found gaining visibility on Forums can expedite a solution (usually by increasing accountability):

For the past two months our Cox Internet Service has been intermittently terrible; specifically in terms of jitter (latency variation) and packetloss. I have been using PingPlotter to track performance over the past few months and will share links to various snapshots below. The disturbance is evident from Hop 1 (my router) to Hope 2 (First Cox Local Node). This 8-12ms hop often averages 50-100ms, due to large spikes in latency and/or packetloss. This affects any work that is sensitive to latency; namely our conference calls as we work from home, and my son's gaming in the evenings.During the times of greatest congestion it is not possible to work from home, nor use the internet for online gaming.

A significant point here is that this performance is INTERMITTENT! Many times the connection is very stable, with the average ping very near the minimum ping. During some of the worst conditions I have seen "Outages" reported on my Cox Account. However it is often performing poorly shortly after these outages have been cleared.
Because the performance is often GOOD, and appears to be unrelated to any environmental or network use conditions at our house, I suspect Cox has a saturated local node. The IP for this node is
These findings have been obtained on a wired connection.
Is COX aware of intermittent latency/packetloss issues at the local node and when and how will this be resolved?
First, here is a JPG of the current conditions, as I type:

Here are links to various conditions I've captured over the past few months:
Here are examples when everything is GOOD:
I look forward to your response,
