I host my personal site at home with a 15-min battery backup. After that, I accept the downtime. Rarely happens and I haven’t had a single complaint when it does.

Having everything open, on and available 24/7/365 sounds nice until you realize the human toll for things which aren’t that necessary and can be planned around. Down time is a good thing.
doesn’t every website go down when there is no power? ;)
I think the point is to run on solar energy. Being blackout resistant is not an end goal.
Edit: Ohh you're talking about the post title lol
Only if there is no power everywhere. Some run redundancies in multiple locations.
So.... You're saying that if there's no power the website goes down.
I used to work on the website for a utility company that insisted on ridiculous uptime. Our major deployments risked taking the system down for a few seconds, though in practice that never happened.
As a result, they made us do deployments starting at 3:00 in the morning since that was the least active time on the site. Fuuuuuuuuck that place.
The uptime looks better than GitHubs...
I know this is a typo, but I'm sad Guthub isn't a food delivery company.
A disappointment equivalent to Piefed.

"Hey look everyone! We never heard of grid scale batteries!"
This website is like 10 years old from memory, well before grid-scale batteries were widespread (well they still aren't in many countries).
Right, and I'm older than the Sony Walkman and that's why I never heard about "internet".

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?
My home server is 100% up, because I run the checks from the same machine
I didn't turn it down, so it's obviously up.

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.
My brother is an air traffic controller at one of the world's busiest international airports and I can assure your their system uptime is no where close to 3 9s.

100% uptime since the last time we turned it on!
Companies claiming 99.9999 uptime is an absurd goal for a SLA, and wouldn’t even survive a small internet outage like a DDoS attack or Akamai outage. I remember in the 90s selling the idea of 5 9’s - 99.999% on my resume until some manager who Interviewed me asked me to state the expected downtime. I stopped claiming that number because it’s impossible without full active redundancy in different locations and not dependent on external providers like cloudflare ever going down.
And please don’t argue maintenance windows “cover it” because that’s not how they work in the real world today.
Downtime per year:
- 99% ~3.65 days (5,256 min)
- 99.9% ~8.77 hours (526 min)
- 99.99% ~52.6 min
- 99.999% ~5.26 min
- 99.9999% ~31.5 seconds
For my home lab I’m happy my stuff is online and content I hardly lose access when there’s a power outage thanks to my ups. But if I tracked I’d be closer to 95%. Good enough but I can’t wait till I just don’t care to run anything.

Over a period of roughly one year (351 days, from 12 December 2018 to 28 November 2019) the server was up for 95.26% of the time. This means that we were offline for 399 hours (which corresponds to 16.64 days).
Not bad at all really, at least for non-mission critical sites. I have solar and I really like it. Solar power on two barns, and a lot of my security cams run on solar. I'm not sure if it's the formatting of this site, or the grainy pictures, but it oddly reminds me of the Trojan Room coffee pot.

Of course, it depends on the website. I'd be unhappy if my banking site went down for more than a day.
ihavenotv.com could go down for weeks, and I wouldn't fret it.
This is actually great!
Social media sites should do this. There's never a good reason to be on [Insert Corporate Slop Social Media Website here] at 3AM.
Never a good reason, like different timezones, different working/sleeping hours. Theres no better or worse hour for every single person.
It's not like those major social media sites don't have some kind of data center (or rent one) in every "major" (population wise) timezone they operate in. Your other arguments still hold true, but I think even then it would be better for all of us if those websites went down every now and then.

This was cool 5 years ago, now you can get solar panels and a home battery big enough to power this thing 24x7 without an issue, even if the sun was fully blacked out for a week
edit: a 40kwh battery would last with the power draw:
Power usage 2.62W
like over a year
A 40Kwh battery is like 10 grand, I'm not sure why you brought that up. I'd be more likely to invest in a second battery and solar panel. It's been up for over 23 weeks right now, I'd guess a second solar panel and battery could keeping it up nearly 100% of the time, and it'd cost under $100 for a 200wh battery and 30w panel.
Now they can get better hardware, but should they? They take seriously the low tech part, and part of being low tech is fighting against consumerism culture and keeping with what they have, which is wotking fine
There's a lot of articles about supply based usage vs demand based energy production on that website. The idea that it turns off every now and then is sort of part of the authors' intention of showing "we can live with some outages".
This article in particular is a good one: https://solar.lowtechmagazine.com/2017/09/how-not-to-run-a-modern-society-on-solar-and-wind-power-alone/

Interesting concept. I haven't seen lowtechmagazine before, going to have to definitely check it out.
I spin down our development environments when they have sit idle for a period of time, not at all the same but makes me think deeper about the entire concept.
Update: This is a really cool website. I see some fun projects here too that I could have my kids work on!
It's nearly 20 years old. Originally a Belgian site only available on the .be domain.
His blog got integrated in an other website for a while but then came back to www.lowtech.be after some years.

There's a nifty project on Mastodon where someone is running an instance entirely on solar (and I think a battery?). They've been tinkering with some of the code to do things like optimise images for reduced weight or CPU cost.
The project is called @solaradmin@solarcene.community and the account for the person running it is on a separate instance, presumably so people can message them about problems: @smallsolar@techhub.social.
congrats guys! we killed it!
It's honestly impressive what you can do with under 3W of power these days

I love Low Tech magazine! I have been reading them for years.
