Is this the first time this system has failed so spectacularly? While the failure is notable, it does speak to the uptime of this system.
Not exactly that we need to praise them or anything, but I think sarcastic tone in some replies ("if only they did something BASIC") aren't needed.
Ideally you would want the combination of both: system doesn't usually crash/fail, but you force it to do so regularly. See https://en.wikipedia.org/wiki/Chaos_engineering
If it had uptime of 2 days but only went down for a minute at a time that would not be a problem
