This. People working in IT naturally think keeping IT systems up 100% time is most important. And depending on the business it often is, but it all costs money. Running a business is about managing costs and risks.
- Is it worth to spend 20% more on IT to keep our site up 99.99% vs 99%?
- Is it worth to have 3 suppliers for every part that our business depends, with each of them being contracted to be able to supply 2x more, in case other supplier has issues? And pay a big premium for that?
- Is it worth to have offices across the globe, fully staffed and trained to be able to take on any problem, in case there's big electrical outage/pandemic/etc in other part of the world?
I'm not saying that some of those outages aren't results of clowny/incompetent design. But "site sometimes goes down" can be often a very valid option.
