Some acceptable level of loss is fine for 99.99% of Netflix's user base just like cable, electricity and running water I suffer a few hours of losses each year from those services it suck yes, is it the end of the world no..

Actually calculating - understanding - cost of downtime, and what variations on that exist over time, are keys to reliability engineering.

But if you plan to cover X failure scenarios and only cover X/2 failure scenarios due to implementation glitches you goofed.

The right answer may be "relax and accept the downtime" and it may be "spend $10 million dollars to avoid most of these".  If you haven't thought it through and quantified, do so...
