I run a nonprofit that teaches people how to code and for the past year we have hosted our own server / content at our offices. our students ssh into our server to write code and host their apps / content from there. Sometimes, Ive noticed that even though it feels like internet is down, upload still works and students can still ssh into our server remotely. In the past year we haven't had any issues at all, except for the time we accidentally tripped the power cord. Hosting your own content might be alot more reliable than you think :)
One of the things I've noticed with on-prem equipment at work, is that when the Internet has gone down in the past, most people don't actually... notice. The scenario is obviously very different than a home user, because multiple users can still communicate amongst the organization with outside Internet down, but there's huge benefits to being on-prem that have gotten disregarded or forgotten about.
A consumer-grade UPS on my home PC and network equipment has reliably kept my home setup reliably up and connected for all except for ISP outages.
