Deployments

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.
