yes 3 years without hardware reset of a component not designed for long term high reliably use is irresponsible (the are servers fir very high reliability, they are just WAY more expensive)

BUT this doesn't mean you need to have downtime, in the same way a train unit in a railway system going through maintenance doesn't mean your railway system has downtime.

Redundancy is a must have feature for reliable systems and that means you system must be able to cope with random hardware failure or rebooting a server unit.

And both planned and unplanned maintenance of components are important normal business which in a well desingned reliable system should not lead to downtime.

Similar testing failure cases is important and should be done.

so either you don't run a high reliably system (and likely don't run into this bug ever), or you run a proper reliable system (and it's not a big deal), or you run a badly desingned or operated system pretending to be high reliably but but really being that... which is irresponsible (if you are aware)
