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.

There are plentiful scenarios where 10 minutes of sequential downtime would be a critical issue. Say you’re a telecoms or internet provider - even a one minute delay to a life-saving message can be enough for someone to die.
Furthermore, lots of things are interconnected now. Your business might be able to handle 10 minutes of downtime, but lets say my business relies on 12 different service providers like you, who each have 10 minutes of downtime during a week using your rationale. That could up being 2hrs of downtime each week.
99.999% is about 5 minutes and 16 seconds of downtime per year.
12 services down perfectly sequentially works out to 76 minutes per year, not 2hours per week.
Not saying there aren’t applications where that can’t be catastrophic, but you’re scale is off for three 9 downtime.
Yes, there are some that do, I should have said that. But the number of orgs that need extreme uptime is so small compared to business that think they do need it but really don’t.
My home server is 100% up, because I never check it and that’s how it works, right?
I didn’t turn it down, so it’s obviously up.

I host home assistant and if anything goes down I’ll notice pretty fast.
Hospitals? Air traffic control? Power grid operators? Like these are exceptional businesses, but they’re out there.
I agree, but the number of business that have actual need for extreme uptime is insignificant compared to the number of businesses that don’t but think for some stupid reason they do.
Many airports are closed at night.
Good point, but that’s planned downtime.
Those do actually go down. Hospitals have to be evacuated after an earthquake, airports force all aircraft to divert or the grid has the sort of outage that gets it’s own Wikipedia page and needs to be black started.
