Friday Deploy

Noun · Taboo · Hacker Culture

Definitions

  1. Deploying code changes to production on a Friday — universally regarded as reckless because if something breaks, you either ruin your weekend fixing it or leave it broken until Monday. The first commandment of DevOps: thou shalt not deploy on Friday.

    In plain English: Pushing new code live on Friday afternoon, considered terrible practice because if it breaks, your weekend is ruined.

  2. The counterargument: if your CI/CD pipeline, monitoring, and rollback mechanisms are solid enough, deploy day shouldn't matter. Companies with mature deployment practices deploy continuously, including Fridays. The fear of Friday deploys is a symptom of unreliable systems.

    Example: 'We deploy on Fridays. We also deploy on every other day. If your pipeline can't handle a Friday deploy, fix your pipeline, not your calendar.'
