[author] There were a number of critical parts of the chain responsible for FB Ads revenue. It all started at the UI or API (which were 75% and ~25% of FB revenue when I left in 2017). Then you had the DB layer, managed by another team, the AI/Targeting layer and one or two others.
If any had failed fundamentally, FB was in big trouble. However, other than Power Editor and Chrome, the rest all ran in our data centers and were under our control.
