It's a matter of tradeoffs. If your webapp is unusable 2 days a year people will just do something else in the meantime.
If your flight control software fails for two days a year planes might come crashing down.
The former is tolerable even if unpleasant from a customer perspective, thus they don't pay for flight control levels of reliability.
And it's not like this is unique to software. It's the difference between a disposable plastic fork and surgical instruments.
- Gravityloss 8y agoYes, I agree. I was wildly exaggerating. Life sustaining equipment is regulated and has a lot of resources spent on it to make it reliable. And toy software doesn't matter if it falls down. I guess medium level services fall in between. Still causing inconvenience and monetary losses when they fail.
