generated: '2026-07-21'
method: probed
source: live DNS/TLS/HTTP probes of legacy UUNET domains (uu.net, uunet.com, uunet.net)
note: UUNET is a defunct brand (folded into Verizon Business). Its legacy DNS zones
  remain operated by Verizon; web hosts serve only an HTTP 301 redirect to
  https://www.verizon.com/business/ and do not serve HTTPS at all. Absence of
  records below is real probed data, not a gap in probing.
