  dig + curl/openssl against 4cinsights.com, 4C Insights' own registrable domain, on
  2026-09-05. probe-domain-security.py returned "no-hosts" because apis.yml carries no
  Website/baseURL for a defunct company, so this file was probed by hand against the
  domain the company itself used.
note: >-
  The domain survives the company. It resolves (AWS Route 53 nameservers, two A records)
  and terminates on an AWS elastic load balancer that answers only on port 80 and 301s
  every path to http://flashtalking.com/social. There is NO HTTPS listener at all — a TLS
  connect to 443 times out on both the apex and www — which is unusual and is itself the
  finding: the surviving redirect was never given a certificate. Mail is still live and
  routed through Proofpoint, with SPF published (Google + Outlook + Pardot + SparkPost)
  and no DMARC record. Infrastructure and mail routing both belong to the acquirer, not
  to 4C.
