This task is part of WE6.4.4 Mobile domain sunsetting ([FY25-26 Q1](https://meta.wikimedia.org/wiki/Wikimedia_Foundation_Annual_Plan/2025-2026/Product_%26_Technology_OKRs#Q1)), as tracked by the parent task T214998. ------- Hypothesis as published in July 2025: > If we unify our domains by serving all page views on MediaWiki sites through a canonical domain, then we will reduce platform complexity and Search Engine Optimization (SEO) risks by eliminating the mobile-subdomain redirect. Completion is measured by increasing mobile page views on canonical domains from 0% to 100%. ## Work * [ ] Write Hadoop query that measures the completion metric, and run it for July 2025 and August 2025 to set our baseline. * [ ] A week after the pilot rollout (T401595), run it for the pilot wiki, and validate the basic working of the query and the change. * [ ] Decide on which wikis and wiki families to check as milestones. * [ ] During the main rollout (T403510), run it every few weeks for the week before/after the change on a given wiki, and validate the change, looking for anything unexpected that might prevent us from reaching our target.
