Sources and verification

Shutdown: The rendered first-party landing page states a completed shutdown on May 4, not a future deadline. This is the actual service-end day, not an inferred proxy. The original announcement date, cutoff hour and time zone are unspecified. The record covers the separate Mariner task experience, not Gemini, AI Mode or later products using its technology.

Launch: Google’s May 20, 2025 article confirms availability to Google AI Ultra subscribers in the United States. This is the public subscription offering; the December 2024 research prototype was limited to trusted testers.
Location: United States · Mountain View. Google’s March 2026 Workspace Updates page lists its Mountain View contact address. This records the operator’s historical contact city, not a Mariner team office or service market. Existing sourced Census city coordinates are reused at two-decimal precision. Location source
