The site doesn't go down very often TBO. - Power shortages: happens 3x per year for 20 minutes or so. The server boots up automatically after that. - DDOS: I have cloudflare. I have the server under monitoring. I have Mikrotik router. - Hijacking: I use a Mikrotik router on the edge which has a pretty solid firewall (+ Cloudflare). It's good to have something like that in your household regardless of your web hosting needs. It’s just a matter of paying some attention to your own internet security. - Active maintenance: I don't do that, lol.
It's so simple to setup all of that (server, linux, docker, cloudflare, firewall), that I think everyone should at least try. And it's fun, not an obligation.
I plan to increase the amount of services I'm going to host myself in the future. You can't go wrong choosing freedom.
Said that, I understant the hesitation someone might have when dealign with the problem for the first time. My point is that it’s worth to take that step.
PS: the overall availability of the service is good enough on my setup to not be penalized by Google's SEO platform (that's a thing if you have persistent hosting issues).
