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

Getting started

If you need help, contact Release Engineering on IRC at #wikimedia-releng ^connect; and ping Tyler (thcipriani).

• MediaWiki is deployed weekly through the Deployment Train. Other services follow their own schedule.
• Times are pinned to San Francisco, thus the UTC time changes in March and November per DST.

• Prefer regular Backport windows over adding new windows. To request deployment of a config change or backport, add your username and Gerrit URL to one of the backport windows on this page. You must be online in #wikimedia-operations on IRC during your deployment and install WikimediaDebug ahead of time.
• Tasks that meet Inclusion criteria require their own windows, which includes long-running tasks. Schedule more time than you think you need to account for delays and set backs, we recommend one hour for most tasks.
  • To create or modify a recurring deploy window, send a patchset to deployments-calendar.yaml file in repos/releng/release.git.
  • Announce changes to the ops mailing list ahead of time if they are likely to affect HTTP caching, introduce new cookies, or utilize new database tables.
  • Announce deployments of major features to the community via Tech News and/or via other Product communication channels.
• 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.
