DigiCert PKI Infrastructure Domain

symcd.com is a critical Public Key Infrastructure (PKI) domain operated by DigiCert, one of the world's largest Certificate Authorities. The domain name derives from "Symantec Certificate Distribution" — a legacy from Symantec's Website Security business, which DigiCert acquired in 2017.

Purpose

This domain serves as infrastructure for SSL/TLS certificate validation services:

  • OCSP Responders — Online Certificate Status Protocol endpoints (e.g., s.symcd.com) that allow browsers to verify if a certificate has been revoked in real-time
  • CRL Distribution — Certificate Revocation List hosting for certificates that need offline revocation checking
  • Certificate Chains — Intermediate certificate distribution for trust chain validation

The domain's high traffic rank (Tranco #3,681) reflects its role in billions of daily certificate validation requests from web browsers worldwide.

DNS Infrastructure

  • Authoritative Nameservers: Redundant configuration using both UltraDNS (pdns196.ultradns.) and DigiCert's own DNS infrastructure (ns20-25.digicertdns.)
  • Primary Contact: dns@digicertdns.com
  • Subdomains: 52+ including s.symcd.com (OCSP), g.symcd.com, tc.symcd.com
  • DNSSEC: Not enabled
  • IPv4/IPv6: Dual-stack support on all nameservers

Technical Notes

The domain itself does not host a website — it exists purely for PKI operations. Subdomains like s.symcd.com resolve to DigiCert's OCSP infrastructure (pki-ocsp.digicert.com), handling certificate status queries for millions of Symantec-legacy and DigiCert-issued certificates still in use across the internet.
