Weekly (if not more) service outages in AZ

I've always hated cox, but now forced to use it in our new residential area. Why is there always a service outage at least once a week that causes our internet to go down? Without fail, there's an outage for a few hours 1-2 times a week. If it's a planned outage, why not do it in the middle of the night when most people are sleeping, and not during the day when we have work?  Why am I paying for a service that gives me no service 1-2 days/week?
