Deployment freezes are (should be) completely normal and justifiable.

Do you really think that Amazon is deploying (non-emergency/operational) code changes during BFCM or re:Invent? Or that Fox/CBS/NBC are deploying code changes during the Super Bowl?

Also (unless you have some business need to deploy before the weekend) why deploy on a Friday afternoon? You're just asking for latent defects to page you in over the weekend. Save yourself the trouble and delay that deployment till Monday morning. Your team will thank you in the long run.

Sometimes repetitional and/or sleep damage isn't worth being uncompromising on idyllic CI/CD goals.
