Constant disconnects

I am generally happy with my Cox internet service here in the Phoenix Metro Area. I've not had problems, even when my wife and I started working from home. I am a Business Analyst for a major foodservice company, and am constantly connected to large databases or in video conferences. My wife is a elementary school teacher currently teaching remotely so she is in a video conference with her students for a large part of the day. Outside of work I am hobby streamer on Twitch, and I consume lots of streamed content. I tell you all this because I want to set a baseline of what I am doing with my service.

I'm not on Gigablast (we're on Premier 200) because there only two of us in the house, and outside of working we rarely are making heavy use of our network at the same time. I have a Cisco DPC3010 modem that I purchased from COX a couple of years ago.As I said, I've had pretty flawless service to this point but over the past few days I am experiencing constant internet disconnects. When it happens every device on the network is affected. These instances usually last only a few seconds, but it's long enough to close VPN connections, and disrupt video conferences.

I run through all the steps on the support page. Router and modem have been reset multiple times. I've tried hard wiring into the modem. Nothing is helping. It feels like the problem, whatever it is, is happening somewhere before the modem. We did have a large storm, with fairly violent wind, roll through the night before all this started, so I tend to think its related.

Any help you all can provide would be greatly appreciated.
