Multiple Outages Every Day

We have been having outages every day, multiple times a day for the past month or so. Starting around 9AM til 9PM. Loss of signal on the modem. Usually lasts anywhere from 2 minutes to 3 hours. I have called multiple times, once I was told there was some work and they have constantly "closed my tech visit" for me because of this. Some have tried to blame the modem (which is mine) but this only happens during the day time hours. Its completely stable after 9PM or so.

What work is being done, and when can we expect to have a reasonably stable Internet connection again?

I've begun monitoring, and below is just a week. Its also testing every 5 minutes so its not catching the tiny blips.
