A solar powered website that goes offline when there's no power

This website made me reconsider if 99.9999% SLA and always online is really that important for lots of websites. I used to self-host my own server in my own apartment, but gave up on that after my internet provider had their first major outage that lasted almost a week. Also I didn’t want to worry about the fire hazard, or the server going down when I was traveling etc.

But a solar powered server seems interesting, if the batteries could be made fire safe.

I have never been a fan of anything above 3 nines of uptime even in a business situation.

Your business will not collapse because of 10 min of downtime a week, and if it does that is not technologies fault.

I don’t even bother to track my home setup.

My home server is 100% up, because I never check it and that’s how it works, right?
