  This is a CORPORATE lifecycle record, not an API versioning policy. CH2M Hill
  publishes no API, so there is no versioning scheme, no deprecation header
  policy, no SLA and no status page to record. What there is, and what a reader
  of this profile needs, is the end-of-life of the brand itself.

      The CH2M brand domains have been fully decommissioned. ch2mhill.com and
      ch2m.com resolve to a shared parking address (107.22.178.157) that answers
      HTTP 404 "Web Site Not Found" for every path including the site root, and
      www.ch2mhill.com does not resolve at all — its CNAME target is the literal
      string "107.22.178.157.", an IP address written into a CNAME record, which
      makes the hostname NXDOMAIN. No redirect to jacobs.com was configured, so
      every historical inbound link to the CH2M site is broken rather than
      forwarded.
