packet loss

I have been experiencing severe latency spikes and jitter on my connection for over 2 years at my address and a tech visit almost every couple months from you without the issue ever being resolved.
My modem-to-router ping is stable (0–1ms), but upstream from my CMTS (hop 2) I’m seeing spikes from 25ms up to 300ms.

This indicates congestion or a routing problem on your node.

Please check for node congestion, upstream noise, or CMTS load issues.
I can provide ping and traceroute logs if needed.

so far I get a response from someone new every time they respond with a message and it has taken 30-60+ minutes between any sort of response. Not too optimistic about this form of customer support from comcast.
