yes ad dhork mentions its related to a concept of 6sigma which is an airline/telephony thing about things that must not fail. My little quip is suggesting they work like 90% of the time which is not great.

“Five Nines” typically refers to something that works 99.999% of the time, which still allows for 1 screw-up out of 100,000.

Huh truly a TIL. Never heard this in my life.

I learned it working telecom. For example, if you wish to offer 911 service, your service has to be operational 99.999% of the time.
It’s more casually used to mean a service or operation is insanely reliable.
