Etsy 现在的 CTO 前几年写的文章。production 出故障了,人们经常一厢情愿地想找出有且仅有一个 root cause,这样才好向上面交差。复杂的系统出故障了往往不止一个 root cause,有天灾当然也有人祸。

"... failures in complex systems require multiple contributing causes, each necessary but only jointly sufficient."

"Finding the root cause of a failure is like finding a root cause of a success."
