Why We Ship on Fridays

Everyone tells you not to deploy on a Friday. We do it every week, and it has made our releases calmer, not scarier.

The trick isn't bravery — it's the safety net. Every change ships behind a feature flag, so switching it off takes one click and no redeploy. Our rollback runs in under ninety seconds, and we rehearse it monthly. Alerts page a person, not a dashboard nobody is watching.

Friday also keeps us honest. If a change feels too risky to ship before the weekend, that's not a scheduling problem — it's a sign the change is too big or the tests are too thin. So we split it, cover it, and ship it Friday anyway.

Small, reversible, observable. That's the whole policy.
