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

Getting started

Ensure you joined the #wikimedia-operations ^connect IRC channel as all deployment-related communications happen there. 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. The #wikimedia-operations channel requires you to register your nickname before you can join.
  • You can use the backport scheduling tool to more easily edit this page:
    Schedule a backport
• 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.
  • To create an one-off window, simply edit this page accordingly
  • Announce changes to the ops mailing list ahead of time if you anticipate or are uncertain about noticeable impacts to database load, HTTP caching, or the introduction of new cookies.
  • 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.

Subscribe in Google Calendar via wikimedia.org_rudis09ii2mm5fk4hgdjeh1u64@group.calendar.google.com.
This may not include one-off windows. If there are differences, then the wiki page is canonical and correct.
