Deployments

Some notes about the deployment windows

• It is good to ask for a little more time than what you think you'll need to do all of the deployment and testing; you never know what issues will come up and slow you down.
  • Generally, we have found one hour windows to be a good size for most things.
• Deployment windows are 'pinned' to the time in San Francisco and thus the UTC time will change due to the United States observance of Daylight Savings Time as appropriate.
• SWAT deploys happen twice daily (8am and 4pm Pacific) and are for pushing out simple, quick, and low risk changes (as assessed by you, members of the SWAT team, and the Release Manager).

For detailed instructions on how to actually deploy code to the Wikimedia servers, see How to deploy code.

This page tracks planned deployments of software to the Wikimedia Foundation servers that host the various Wikimedia project wikis (Wikipedias, Wiktionaries, Wikiversities, Wikimedia Commons, etc.).

Cadence

The Wikimedia Foundation currently follows a one-week deploy cadence. This means that there is one week between updates to any one Wikimedia project site wiki (excluding urgent fixes, of course).

Scheduling

To schedule a deploy window, or if you see a potential conflict with your upcoming deployment, please e-mail Greg Grossmeier.

Inclusion criteria

See the list at Inclusion criteria for the kinds of changes that require scheduling here.

Communicating

• Every major or new feature deployment should be announced on the Wikimedia blog and/or Tech News (use the "user-notice" tag on Phabricator) and/or global on-wiki delivery. For routine and maintenance deployments, listing your change here is enough.
• Changes that are liable to affect site performance or infrastructure should be announced on the ops mailing list. This includes anything that alters caching behavior, introduces cookies, substantially increases the static asset payload, or adds new and complicated query patterns.
