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.

This may not include one-off windows. If there are differences, then the wiki page is canonical and correct .
