Here we go again, part 4

Like clockwork, 8 weeks after the last repair order for T3 timeouts and packet loss, the problem has returned. I can practically set my watch by it at this point. My connection works well for 2 months after the service appointment then starts having problems again. I predicted this in my last post, and it turns out I was correct. As I've mentioned before, this problem is always in the Cox plant and never in my equipment or premises wiring.

It's not too bad at the moment since I caught it when it was first starting, but problems like this never go away on their own and always get worse by the day:

01/13/2021 10:11 82000500 3 "Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=(redacted);CMTS-MAC=(redacted);CM-QOS=1.1;CM-VER=3.1;"

I'll initiate a service call when it gets bad enough for the tech to be able to easily identify the issue, but it seems like I shouldn't have to keep doing this. What does Cox do every 8 weeks that could be causing this? Wouldn't they save money by correcting that procedure instead of requiring home service calls every 8 weeks to fix their network issues?
