note: >-
  RRD serves exactly one well-known document: an RFC 9116 security.txt on
  www.rrd.com. Every other well-known path on that host returns the site's
  standard HTML 404 page. connectone.rrd.com — the ConnectOne customer
  storefront — answers 401 on every path including /.well-known/*, so nothing
  there is anonymously readable. api.rrd.com resolves (162.27.32.131) but both
  443 and 80 are closed/filtered from the public internet.

    note: >-
      DNS resolves to 40.70.68.247 (Azure); TCP 443 refuses connections from two
      independent networks. Search engines index an RRD-authored page at
      https://intl.rrd.com/Help titled "RR Donnelley API", so the host does serve
      RRD API help to somebody — just not to the anonymous public internet.
