Casa Grande, AZ Full Day Drops

I’m in Casa Grande, AZ. Cox used to be the best ISP choice because Centurylink (the cheaper one) was always going down. That has changed. Now Centurylink doesn’t go down and there’s been at least 6 major outages in the last month with Cox. My question: What has changed in Casa Grande that is causing the outages? I haven’t heard any communication from Cox.
