Frequent short internet outages

For the last month or so, we have a large number of short internet outages. I recently replaced my modem to see if this would fix the issue, but it has not. About a year ago I was having latency issues and the techs replaced all the coax, including the coax from the street to my home. It had been working well until recently. 

For example, from 12-1:30 today, I've had 9 outages, some as short as 10 seconds, others as long as 40 seconds. All devices lose all connectivity. (Zoom meetings drop, games disconnect, ect.) 

I have been tracking my connectivity, the red bars indicate the internet is down.

48HR: some of the short outages don't' even show, but you can see how often connectivity is lost: https://imgur.com/7TUO1NK

Any suggestions appreciated.
