The tax and eHealth systems have the advantage of being monopolies though, it's not like you can go to another tax service with better ICT (except by emigrating of course), and it's literally illegal to not use the system at all (because you have to pay your taxes), so you can't even choose not to use it. Most companies do have competitors, so "we are more reliable" becomes a selling point for them. Definitely agree that some companies take their uptime demands beyond the point of diminishing returns though. I once worked at a company which would absolutely not allow 10 minutes of scheduled downtime in the middle of the night but didn't mind at all if I took several months to build a workaround.
