Awesome write up as usual John. I'm no expert so I was wondering: "In the initial moments of the outage there was speculation it was an attack of some type we’d never seen before." - Is there a reason you would go to this first vs checking the last lot of code deploys first/and or at the same time?
It was speculation. We were looking at sudden massive CPU use all over the world. Since we do staged deploys that shouldn't happen yet...

I assume this is why :D
