Ok, just playing devil's advocate here. How many FAANG companies have you seen have an outage this year? What's their budget?

I think a better way to reply to the author would have been "how often does it fail"?

Every system will have outages, it's just a matter of how much money you can throw at the problem to reduce them.

If 99.995% correct looks bad to users, wait until they see 37%.
