Have a look at what's described in the question about "[Brief outage planned for Wed, May 3, 2017 at 0:00 UTC, 8pm US/Eastern (like a fire drill for computers)][1]"., which is about testing of the existing "**Disaster Recovery Planning**" (= DRP) of the entire family of SE sites.

If you were in charge of this, what would be your recommendations to improve these kinds of DRP-testing ... in production?
