Deploy on Fridays, or Don't

Deploy on Fridays, or Don’t.

There seems to be a debate that has gone on for quite some time now on the Twitters about whether or not you should do Friday deploys, and whether there should be Friday moratoriums, etc. There are a lot of accusations being thrown around about fear, testing, time to recover, and the like. To be very clear, I am not a big fan of Friday deploys. That opinion is not based on merely how I feel about deploying on Friday, but also based on the science of it, as well as my learned experience.
