Packet loss affecting everyone in the area again

Late 2018 into 2019, this area started having critical packet loss issues that would cause constant buffering in all videos and live streams (Youtube, Hulu, Netflix, Twitch) among all devices plugged and wireless. It took 8+ months of me calling and scheduling techs onsite to record the errors and escalate the issue to the maintenance team. It took reshielding of cables, replacing a faulty amplifier and hardware replacements at the node to resolve the issue. As of a couple weeks ago I noticed the area again experiencing the same issues, buffering videos, slow web browsing, etc... I checked the modem and again there are T3 timeouts in the logs. I ran several ping test to the local Comcast gateway and to Cloudflare DNS server, both confirmed packet loss around 2-6%, attached are the recent screenshots I took. I had an original thread going back to last year on this forum titled: "Packet loss affecting everyone in the area". I was attempting to reopen the same thread but the thread does not load - url: https://forums.xfinity.com/t5/Internet-Archive/Packet-loss-affecting-everyone-in-the-area/m-p/3213995#M607624

Also new modem was purchased recently, diagnosed with Motorola support and they did not find any errors and stated it was coming from the ISP's end. The packet loss issue comes and goes, the recent ping test was from 8:45PM EST on 9/20/20. Can a tech please look into this?
