I'm having this same issue and have been logging 24 hours a day. I wrote a script to only log latency events above 30 ms, which is generous for the first hop of the network. In a 24 hour period I've logged 14,000 events.
I've had the guys out to the house to check from the pole to the house (checks out fine). They checked from the pole to the node (checked out fine).
I ran a histogram chart, based on time blocks, to see if there are any trends and sure enough there is. Between 12:30am and 6:30 am are minimal events, below 10. After that it sky rockets. This suggests MAJOR congestion (Cox says it's Covid19 induced). To be clear my total bandwidth on my gigablast is acceptable (usually from 700 to 900 Mbps), it's just the latency that is terrible.
Its affecting my online game playing at my video conference calls. Long story short, they can't fix the issue until life normalizes.
