running a commercial VPS in a datacenter has a ton of advantages, but i'm guessing that the guy with a footer like this doesn't really care about them. running your website off a raspi in your living room is cool, wheher it's the most practical solution or not doesn't really matter.
Maybe a raspberry pi behind my sofa isn't so stupid?
Of course you could use multi-cloud/multi-azs, but do you really WANT to for a personal website?
I can't remember the last time my little nano server in US-West-2 has been down.
