notes: >-
  collaborate.com no longer hosts a product. Plain HTTP returns 301 to
  https://www.webex.com/ (Cisco Webex); HTTPS on the apex times out and serves
  no site of its own. Nameservers are MarkMonitor, consistent with a
  brand-protection / redirect domain held by the acquirer rather than an
  operating company. Absence of records below is recorded fact, not a gap in
  the probe.
