Constant drop 8am to 11am, 8pm+

I need an immediate escalation to Line Maintenance / Network Engineering for an area infrastructure issue. I am tracking my modem diagnostics on a Nighthawk CM3000 and my downstream is perfectly fine, but my upstream is severely impaired.

My event logs are continuously flooding with CM-STATUS Event Type Code 1 (MDD loss) and Code 4 (UCD loss), alongside Critical T3 Timeouts that correlate exactly with total upstream dropouts during peak hours.

Furthermore, looking at my signal page, Upstream Channel 5 is degraded at 31 dBmV, Channel 6 cannot lock at all, and my Upstream OFDMA channels are completely failing to lock.

Because a field tech has already replaced my drop lines and cables, this is confirmed Node-Level Ingress (noise on the return path) or an over-capacity neighborhood node. Please bypass standard troubleshooting and open a Line Maintenance ticket to check the neighborhood plant.
