Frequent short internet outages

Question

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.&nbsp;
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.)&nbsp;
I have been tracking my connectivity, the red bars indicate the internet is down.

1HR: example from today:&nbsp;https://imgur.com/dwGaFgv
48HR: some of the short outages don't' even show, but you can see how often connectivity is lost:&nbsp;https://imgur.com/7TUO1NK
Any suggestions appreciated.&nbsp;

I have the same problem, but my connection drops a lot more often. Seems every other web page I load I have to wait as the connection keeps dropping.&nbsp;
