What Is a Deployment Window?
A deployment window is a defined span of time during which deployments to an environment are permitted. Windows are picked to align with low traffic and the availability of people who can respond if something breaks. Outside the window, releases are blocked or require an exception.
Why it matters
Shipping during peak traffic or when no one is around to react amplifies the blast radius of a bad release. Constraining deploys to a window concentrates risk into a monitored period. The trade-off is reduced flexibility, which teams with strong automated rollback often relax in favor of deploying any time.
