This page tracks upcoming deployments of software to the Wikimedia Foundation servers.

• Cadence: MediaWiki follows a weekly deploy cadence known as the Deployment Train, except for backports. For other services, teams decide their own schedule.
• Schedule: Generally use Backport windows instead of scheduling new windows. But, long running tasks and others things covered by Inclusion criteria do require their own windows. When creating windows, schedule more time than you think you need, to account for issues that might slow you down. One hour is best for most things.
• Requesting a change: Add your username and URL to Gerrit patch in the backport window you want to utilize in the table below. When requesting a change you must be present in the wikimedia-operations IRC channel at the given time and setup with the WikimediaDebug tool.
• Times are pinned to San Francisco, and thus the UTC time changes in March and November due to the DST.
• To add or remove your name from the list, or to schedule a new recurring deploy window, send a patchset to mediawiki/tools/release.git's deployments-calendar.yaml file. Add thcipriani as a reviewer.
• If you need help, contact Release Engineering on IRC at #wikimedia-releng ^connect; and ping Tyler (thcipriani).
• Communicating to engineers: Changes that are likely to affect cache behavior, add new cookies, or utilize new database tables, should be announced on the ops mailing list first. Also consider writing a technical blog post about your efforts.
• Communicating to movement: Deployments of new or major features should be announced on Tech News, and/or as a global MassMessage to relevant communities, and/or in other applicable venues.
• Something went wrong? See Incident response. Is there a user-impacting problem? Communicate in the #wikimedia-operations ^connect IRC channel. If there is a Phabricator task, ensure #Wikimedia-Incident is tagged, and consider setting the Unbreak Now priority.
• For information about the current status of the versions deployed to the various wikis, see https://versions.toolforge.org/
• The deployment commands helper can assist with which commands to run, including how to revert your changeː https://deploy-commands.toolforge.org/
