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 two-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.
  • If your deployment is simple, quick, and low risk (as assessed by you, your team, and the Release Manager) you can sign up for a "SWAT deploy" which is a twice-daily (except Fridays) 30 minute window for those quick, simple, and low risk deploys. Please read the corresponding SWAT deploys page on how to use these.

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). You can see the current cadence, including which wikis are updated on what days, on the /One week page.
Scheduling
To schedule a deploy window, or if you see a potential conflict with your upcoming deployment, please e-mail Greg Grossmeier (or catch him on IRC, his nickname is greg-g).
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 and/or global on-wiki delivery; you can ask Guillaume Paumier for support, including if you're not sure what channel(s) to use. 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.
