> This leads to fun tech support calls if you use your own equipment where you're basically proving to the support underling that you know how to run your equipment for the first 20-30 minutes
For analyzing support burden, I think the relevant question here is why have you even had the experience of calling tech support for a non-working connection - and that falls squarely on the non-reliability of Comcast's network.
Comcast killed my Internet during an interview video call.
Called them to ask why, and they said it was a planned outage. When was it planned, I asked? 17 minutes ago.
Exactly. That's the kind of logic that only makes sense in a metastasized corpo. The only times my non-incumbent fiber connection has gone down in 8 years have been overnight maintenance windows that only happen maybe a few times per year.
