Why we deploy on Fridays

Shipping on a Friday earned its bad reputation honestly. But the real problem was never the day of the week — it was that a deploy used to be a one-way door. When you can roll back in seconds, Fridays stop being scary.

Immutable deploys change the math

On LaunchPad, every deploy is an immutable, addressable artifact. The previous release never disappears, so reverting isn’t a rebuild or a redeploy — it’s repointing traffic at something that already exists and is already healthy. That takes seconds and zero downtime.

A safety net for everyone

Pair instant rollback with automatic health checks and error-budget alerts, and a bad release becomes a non-event: the system can flag a regression, you click revert, and you investigate calmly on Monday. Confidence to ship often is the whole point — and it’s how teams move fast without breaking things.
