Does Facebook ever do postmortems?

  This is what I want to know. I'm not an expert with ChromeTools, but I was able to determine the following: 1. Viewing the page source showed that only maybe a few dozen lines of html were being retrieved. Stopped somewhere in the million scripts in the <head>. 2. More interestingly, the Network pane showed 200s across the board... no resource was being requested that wasn't being served. So, the servers were simply serving up a tenth of the web page? Is that it? It seems as though some internal generation of the html pooped out before finishing. No HTTP errors because nothing in the html that we received requested anything that wasn't already there.

  Publicly? Rarely. (Here's an example, though, from 2010: https://www.facebook.com/notes/facebook-engineering/more-details-on-todays-outage/431441338919 https://www.facebook.com/notes/facebook-engineering/more-det...) Internally? Absolutely, for, at minimum, every user-visible outage.
