notes: >-
  Cask Data's own domain (cask.co) no longer serves the company site — it resolves to a WP Engine
  parking host whose certificate is issued for *.wpengine.com and whose HTTP responses are 404.
  The CDAP documentation host docs.cdap.io serves an expired certificate (expired 2023-09-27) and,
  when the certificate error is bypassed, 301-redirects to the CDAP Confluence wiki. The living,
  healthy host is cdap.io.
