Repeated Modem Resets / Service Interruptions

Almost two weeks ago, I started having an issue with all 3 of our Xfinity services. This includes unresponsive cable and complete loss of phone and internet service. It has happened almost daily, sometimes two or three times. A few times, I happened to be sitting next to the modem when this occurred, and found that the internet connection would go first, then the modem would reset itself. So it's clear that the service interruption is due to the modem resetting itself, as everything comes right back as soon as the reboot finishes. Unrelated to this issue, I also swapped out an older Xfinity modem for the newer XB7 (white) unit. However, the issue persists. A few of the times, the My Xifinity app has shown an "outage in the area", but that does not always show up.

Incidentally, and I'm not sure if it's related or purely a coincidence, this started happening about the same time as a windstorm occurred in my area. A neighbor lost a portion of a tree onto wires, causing the utility wires to sag. It appears that neither Comcast nor Verizon ever came out to tighten up the wires. (Though our service is several poles and a turn away from the sagging wires, and did not appear to be directly affected.) Could that be "shorting" out the service somehow? Or any other ideas what could be causing this?

For reference, here are some of the connection stats from Gateway's control panel.
