Deployments

For instructions on doing deployment, see How to deploy code.

Upcoming major(ish) software deployments and operations changes. For past deployments, please see the archive. For an exhaustive list of past site changes, see Server admin log. For our long-term roadmap, see mw:Roadmap. Please provide UTC times for all deployments (PDT times optional). This page is hosted on wikitech because it needs to be accessible during site outages.

• Scheduling: If you see a potential conflict with your upcoming deployment, please e-mail ops@lists.wikimedia.org to discuss.
• Communicating: Every major or new feature deployment should be announced on the Wikimedia blog; you can ask Guillaume (gpaumier@wikimedia.org) for support. For routine and maintenance deployments, listing them here is enough.
• Schema changes: must be asked on the page before the deployment.

• Reminder - daylight savings time ENDS on 4 November, 2012 at 2am local time, everywhere in the US except AZ and HI! This means PDT will become PST - when recording both UTC and PST times, remember that PST is UTC-8
