If people stop using your site after it's been down once it can't be that good.
Now that's what I call moving the goalposts :) suddenly we're at an hour a day.
Github wasn't the first OSS hosting platform, yet they managed to steal the show, and let me tell you a secret, it wasn't because they had less downtime than others. But if you want to keep telling yourself five nines is of utmost importance to your startup, more power to you.
You are assuming that there is a single thing called downtime (not a scale of slightly bad to outrageous) and a single set of considerations as to whether to move.
Also it may matter less to HN which is a cult following. For a FAANGy type company of course it matters.
But keeping the site up also cost money. So context is really important here. How much money do you spend on the last % of availability vs how much money so you loose on downtime. In my experience people have a more complicated setup then needed because of availability, but at the same time have not tested a real DR scenario.
- if the site is down for more than a few seconds
- if you attempt to access the site during its downtime
- if you pay an ongoing subscription (this could very well be a non-profit site, or one that doesn't primarily drive its revenue from subscriptions)
- if you feel like unsubscribing
How much does this *really* affect a non-moonshot business?
The article explicitly restricts the problem space to top 1000 websites.
I've taken 30 seconds to browse through top 1000 websites and outside of the usual suspects up top, most of them look like https://www.pro-football-reference.com or https://www.tempo.co which to me are not far off blogs and local businesses.
We’re all on redundant internet connections now.
