Friday Deploy
ELI5 — The Vibe Check
A Friday deploy is deploying code to production on a Friday afternoon — universally considered a terrible idea. If something breaks, you're either ruining your weekend or leaving a disaster for Monday. It's the 'swimming after eating' of software development. Some teams have literal rules against it. The bravest (or most foolish) devs do it anyway.
Real Talk
Friday deploys are considered high-risk because production issues discovered after deployment may not be caught until Monday, extending the blast radius. Many teams enforce deployment freezes on Fridays. However, teams with strong CI/CD, monitoring, and on-call practices may deploy any day, arguing that deploy-day restrictions mask underlying process weaknesses.
