Facebook deploy changes to production three times a day? Did I read that right?

  It seems almost every time i use the website something is new/different/broken, so i'd believe that they're deploying that rapidly. The mobile app seems a bit slower, with broken features staying broken for a while. (matching the stated 2 week cycle).

  Yes, they deploy multiple times per day, but this is usually only a subset of the entire application. For example, it might be that the Messaging Component gets deployed today but not tomorrow etc. It feeds into the whole CI/CD, DevOps culture where teams are responsible for independently deploying their piece of the application as often as they feel the need.

  Many business deploy at that sort of rate. But they are deploying independent services

  Facebook gets to decide what Facebook is. They don't have any contract with the user to support a certain feature if they no longer want to, or if they want to change the feature in some breaking way. Most production environments are much more constrained and/or operate under a lot of outside constraints. In those situations you have to be a lot more careful.
