They were just giving their personal comfort threshold.

I mean, technically, one would need to look at the reliability-cost curve. opwieurposiu would almost certainly be fine with eight 9's of reliability if it only cost twice as much as three 9's. The fact that they have a really high risk tolerance in this area don't really undermine their general point.
