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

Cadence:

MediaWiki core follows a one-week deploy cadence (except for urgent fixes). For other services, teams decide their own schedule.

Schedule:

Most changes do not need new deploy windows. Instead, use the Backport windows which happen several times per day most days.

  • Performing a long running task (over 1 hour) must have its own window. See also Inclusion criteria
  • When creating windows, schedule more time than you think you need, to account for issues that might slow you down. Generally, one hour is best for most things.
  • Times are pinned to San Francisco, and thus the UTC time changes in March and November due to the DST.

To schedule a new recurring deploy window, or if you need help, contact Release Engineering on IRC at #wikimedia-releng connect; and ping Greg (greg-g) or Tyler (thcipriani).

Communicating:

Deployments of new or major features should first be announced on the Wikimedia blog, Tech News, and/or global MassMessage to relevant communities.

Changes that are likely to affect cache behaviour, add new cookies, or utilize new database tables, should be announced on the ops mailing list first.

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.
