The tech that just left was the most polite and well versed in all the info I was able to give him, even taking the time to go through my account history to get a full overview of the issue. I was speaking with him outside, properly distanced, as he pulled the line data from the tap. The issue happened to occur right as he begin the test. This is the first time a tech has actually seen the problem first hand, had a ton of jitter peaking at over 350ms, as well as 2% packet loss. Also checked ingress on my end and everything looked great. Hopefully this is the first proper step of many to getting my issues resolved.
Wanted to chime in and say I'm in the same situation on the West side of Phoenix. Had a tech come out who was extremely helpful and even ran a coax from outside into the house straight to the modem to give me all the info to prove it isn't on my end anywhere. He agreed on the node saturation and that a request is put in to resolve the issue but that there is no way to check status or even know if it will ever be honored. My internet becomes nearly unusable between 11am and nearly 9pm. I've been running PingPlotter constantly (bought the program just to collect data) to show that the extreme difference in internet performance throughout the day. On top of everything, I haven't had a speedtest above 500mbps ("upgraded" to Gigablast about 2 months ago) so I attempted to downgrade and it's more expensive to have the Ultimate 300mbps tier. False advertising, poor infrastructure and lack of initiative finally led me to do what @jonathonjoseph said and put in an FCC complaint, for whatever it may accomplish.
steph2109 spread the word my friend, only way to take on giant corporations like Cox is through the FCC as no one individual would be able to drive the change that is needed. After this is all said and done this might hopefully open law makers eyes to the gross negligence allowed due to lack of regulation in favor of the consumer when it comes to broadband communications. Best case we overcome this virus and we get new laws regulating companies like Cox from being able to oversell the infrastructure they actually have in place.
