That must be very annoying.
We used to have a lot of outages with Spectrum (but not daily, though; maybe monthly?), but after we complained for months, Spectrum re-ran the line and gave us Spectrum's newer DOCSIS 3.1 modem (which is free, we later found out), it's been rock-stable.
We've had more power outages than Spectrum outages. Knocking on wood. Coax is a relatively maintenance-heavy versus 100% fiber networks, so Spectrum needs to be on top of it.

Now, we do have Spectrum Business at another location and that is flakier. A few months ago, we had a near-week-long outage, apparently due to this high-split upgrade, but it's been stable since with just a minute or two outages every month.
