Why are you so angry about Facebook, Apple, Google, and Spotify having a tiny outage? They are not life saving services and only cause a mild inconvenience when they fail which practically never happens for most people especially compared to "average software".

> FB themselves have not learned, because this is not the first time this has happened.

They have tens of thousands of engineers likely split into hundreds of different teams/microservices focussing on different parts of their software stack. A ton of them are new to it and nobody knows every part of the stack so shit can happen.

What is the biggest engineering organization size you have worked for and what was your uptime?
