Neighborhood-wide intermittent internet drops after Xfinity maintenance

I need help escalating a recurring neighborhood-network issue to the local network maintenance/outside-plant team. Xfinity performed maintenance/upgrades on September 10, 2026, followed by a near-full-day outage. Since September 11, service has repeatedly dropped for 1–2 minutes across laptops, phones, tablets, TV, apps, and websites.

A technician visited September 20 and replaced the gateway, but the drops continue. The technician said multiple neighbors are experiencing the same issue and that neighborhood hardware or wiring associated with the September 10 work is likely. Repeating modem resets and in-home Wi-Fi troubleshooting has not resolved it.

Please have an official Xfinity employee contact me privately and escalate investigation of the node, tap, amplifier, neighborhood lines, and any equipment changed on September 10. I also need a ticket/reference number, expected follow-up, written confirmation, and review of outage/degraded-service credits, any technician charges, and an appropriate courtesy credit. I work from home, and the instability is materially disruptive. Please do not request private account details in this public thread.
