This probably doesn’t help you unless a competing provider is available to you, but I pay for business class internet just to avoid that issue. I pay double over residential rates, and it’s slower, but I get five static IPs and it’s rock solid uptime and latency because I get QoS’d over all my neighbors. It’s been down for more than an hour only twice in 17 years, and both times were due to cable cuts by construction work in my neighborhood. Even on those cuts my service was restored within 4-6 hours. I get better tech support, and a 4 hour response time for ANY tech issue with the service.
It’s one of the few times I’ve seen that “you get what you pay for” rang so true.
