As pointed out this is from 2015 but I'd love to hear some updated. Has any Facebook employee created newer presentations that discussed, say, their 18,000 iOS classes and the fact that in a single week 429 people contributed to the same iOS app?
I'd also love to hear an update to the "Our site works when the engineers go on holiday" claim.

Isn't this an inevitable outcome once your systems are actually reliable? I've been reading the Google SRE book and they make the same point: every new feature (read: change) is risky. Hence they delay deployments once their "error budget" starts running low.
Seems to me that the only systems that don't work more reliably when the engineers are out are the ones which require hands on deck just to keep them running.
