    note: The original AK Steel investor-relations host ir.aksteel.com no longer publishes a DNS address record (NOERROR,
      no A/AAAA; last Internet Archive capture 2021-10-22), so the pointer was removed rather than left to rot. AK Steel's
      own profile already stated that investor inquiries are directed to Cleveland-Cliffs, the successor entity that completed
      the acquisition on 2020-03-13; the entry now points at that company's live investor page (HTTP 200, verified 2026-08-30).

    is still registered and routes mail to Cleveland-Cliffs'' Microsoft 365 tenant, but the apex, www and ir subdomains publish
