Thou Shalt Not Deploy on Friday

There is a folk wisdom in this industry, written in the blood of ruined weekends: do not deploy on a Friday. It gets passed down like a ghost story, and like most ghost stories it is based on something that genuinely happened to someone.

It is not superstition. It is risk management wearing a meme. The deploy itself is usually fine. It is the 4:55pm “huh, that’s weird” that metastasizes into someone’s Saturday, then their Sunday, then a very quiet Monday standup nobody enjoys.

Deploy when there are people awake, caffeinated, and willing to care if it breaks. Friday afternoon, statistically, is none of those things. Ship it Tuesday morning and give the bug somewhere to land that is not on top of your weekend.
