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 "Lightning Deployment" which is a daily (except Friday) 30 minute window for those quick, simple, and low risk deploys. Please read the corresponding Lightning deployments page on how to utilize 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
The threshold at which something must be scheduled on this calendar is defined as:
  • MediaWiki code updates (including wikitech)
  • Anything going into BetaFeatures
  • going out of BetaFeatures (i.e. will now be included in User Preferences, or as a user-default)
  • new extension (either cluster wide or per wiki)
  • big default behavior changes
  • large schema change
  • anything requiring an outage/read-only
  • anything with a high touch need/likelihood of breakage
    • e.g. changes to deployment system
    • changes that affect load characteristics substantially or in unknown ways, e.g. performance
    • this section is informed by past breakages, as well
  • backend software updates (e.g. PHP, MariaDB, etc)
  • Datacenter changes (e.g. new DC coming online or datacenter going offline)
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.
Schema changes
Any change altering the databases schema must be asked on the schema changes page prior to deployment.
