  Probed 2026-09-06 from a US vantage point. The origin (8.159.144.100, Alibaba Cloud, China)
  is reachable but slow and frequently resets connections from non-browser clients, so the
  shared probe-domain-security.py 5s timeout reported the host unreachable; these values were
  collected by re-running that script's own probe functions with a 45s timeout plus openssl
  s_client and curl. www.acelamicro.com terminates TLS 1.2 with a Let's Encrypt certificate;
  the apex negotiates TLS 1.3. Neither host returns a Strict-Transport-Security header.
  The registrable domain publishes no DNSSEC, no CAA, no SPF and no DMARC record — an absence
  confirmed against authoritative DNS, not a probe timeout. Mail is hosted on Tencent QQ
  Enterprise Mail; with no SPF or DMARC the domain is unprotected against email spoofing.
