Those do actually go down.
That’s the point I’m making: when those examples go down unplanned, in particular hospitals and the power grid, in particular the examples you gave, those can be catastrophic events. I.e., if we ignore planned downtime, then these businesses really need five lines of reliability during the times they are expected to be up.
I agree with the overall point that the average business doesn’t need five nines of availability, but I wanted to point out that there are definitely businesses that do.










Tbh I’m shocked it wasn’t already. Like I thought the border has been a “no rights zone” for as long as I’ve been alive.
