    I have seen something like this a lot. Many more that work fine but but they certainly don’t seem to be at the five 9’s or two nines or maybe even one nine. maybe one nine.

      five 9’s or two nines or maybe even one nine. maybe one nine.

      This is the first time I hear this expression, what does it mean?

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

            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.

        yes as 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.
