Deployments/One week

Summary

The Wikimedia Foundation began using a one-week deploy cycle in June of 2013 and modified in June 2015 to a more simple one. This page describes that cycle. The cycle consists of 3 deploys a week, to three groups of wikis, in 3 phases, starting on Tuesday. This means a version of MediaWiki that starts to go out to the WMF cluster on Tuesday the 7th will be on all WMF-hosted wikis by Thursday the 9th in the same week.
