User:Brennen Bearnes and others from Release Engineering are working on improvements to Wikimedia deployment documentation here. See phab:T273802 for more info.


This is a hub for the deployment of software to the Wikimedia Foundation production servers. MediaWiki follows a weekly deploy cadence known as the Deployment Train, with separate backport windows Monday–Thursday for bugfixes and configuration changes. For other services, teams decide their own schedule. No deploys are allowed Friday–Sunday, with the exception of emergency situations.
