Say it again slowly and clearly, what happened to Facebook?

Many of us remember the horrors of 8/1/14, the day Facebook went down for less than half an hour. A day that lives in infamy. 

I still remember exactly what I was doing. I was on Facebook, reading through my timeline, totally unaware that new statuses and puppy pics would not be added to the top of my feed. I was clueless for the first five minutes. 

That's when I got an email from my colleague, Bob Powers, saying that he thought Facebook might be down. I opened FB in a new tab to check: he was right.
