Hi Chris,

Regarding the URLs of CRLDPs, it is non uncommon for a CA to change the URL of the CRLDP. Obviously, there are redirects until the certificates with the old URL expire. What is the expectation if there are multiple URLs to be included in CCADB?

Coming back to this thread from June 2025, I see several new incidents submitted to bugzilla claiming violation of the CCADB policy which states in section 6.2 that:

/"URLs MUST match exactly as they appear in the certificates issued by the corresponding CA."/

A CA may offer multiple URLs, all pointing to the same full CRL file. As long as the CCADB-reported URL downloads the same file as the URLs embedded in the CRLDP extensions of certificates, what difference does it make?

Historically I've seen CAs changing URLs (for CRL, OCSP, CAIssuer paths) using improved naming schemes, shortening FQDNs, using CDNs, etc. Shouldn't this continue to be allowed?

Would it be reasonable by this community to interpret that the CCADB-reported CRLDP URL reflects the LATEST URL included in newly issued certificates?


Thank you,
Dimitris.
