Some of us are stuck with cable, specifically Spectrum, as there are no other options. We're actually lucky that Spectrum ran cable out to our boonies in the country.
I was/am paying for their 400/20 service. Apparently, at some point, they increased that tier to 500/20, but my speed actually decreased. I used to get 420-430 down and 23-25 up, now I'm lucky to see 320-330 down and 19-21 up. I'm running a 32x8 docsis 3.1 modem that is capable of 1 gbps speeds, so it shouldn't be an issue. Oddly, our internet rarely ever goes out. So, at least it's consistently decent.
Funny thing is there is fiber that runs past the entrance to my neighborhood. They ran it about 2 years ago. No idea who's it is or what it's for. It would be nice if someone offered fiber where I live. I'd jump on it.
