SF South Bay Area - Service has gone from bad to unusable since 3/28 - 3/29 all day outage

I am deeply frustrated about the increasingly unreliable Xfinity internet service I have experienced over the past several years, across multiple residential locations. While I understand that occasional disruptions are inevitable, the frequency and severity of recent outages have become untenable.

Specifically, the all-day outage on March 28-29th marked a significant deterioration in service quality. Since then, I have encountered near-constant intermittent outages, lasting from brief interruptions to extended periods, coupled with drastically reduced upload speeds and unacceptably high latency. This has rendered my internet connection practically unusable for work and daily activities.

As someone with a strong background in home networking, I have thoroughly troubleshot the issue, confirming that it persists even when bypassing my internal Wi-Fi. I find it deeply frustrating that the standard support channels offer only basic troubleshooting steps like router restarts, generic Wi-Fi troubleshooting, or technician dispatches that have proven ineffective in resolving the underlying network problems.

for instance, Internet speeds were stable at 1Gpbs down/25Mps up, decent ping times. The past 2 hours: download varying b/w 2 Mbps to 700Mbps and upload crawling at <2Mbps. 5%-10% packet loss on most ping tests.

I am confident that these are core issues impacting many in my neighborhood. Is there a playbook to help folks like us?

An extremely frustrated, stuck, customer.
