Hi Aaron,

Thanks for the ballot proposal.

I have feedback from our team is it would be great to have 3 months or so to 
make sure that this requirement as addressed properly - “Authoritative OCSP 
responses MUST be available (i.e. the responder MUST NOT respond with the 
"unknown" status) starting no more than 15 minutes after the certificate 
signing operation occurs.”

Could we add in an effective date for this requirement?


Thanks, Bruce.

Subject: [EXTERNAL] [Servercert-wg] Seeking endorsers for Ballot SC-076 
"Clarify and improve OCSP requirements"

This ballot has grown out of discussions around whether OCSP responses must be 
made available for Precertificates, and how quickly they must be made available 
after initial issuance. Much of that conversation is captured in this bugzilla

This ballot has grown out of discussions around whether OCSP responses must be

after initial issuance. Much of that conversation is captured in this bugzilla 
incident<https://urldefense.com/v3/__https:/bugzilla.mozilla.org/show_bug.cgi?id=1905419__;!!FJ-Y8qCqXTj2!dah43yGb4Pf_aNlBECZ6K6S41egFls1ClnimauCXjklwLFBvkfXVPhGQqR7jrEkx27xPuvMsdgZg2YPHI25eSbn38alHzQ$>
 and this Mozilla

In addition, I've often felt like Sections 4.9.9 and 4.9.10 are poorly laid 
out, with little rhyme or reason as to why any particular requirement lives in 
one section or the other. RFC 3647 says that Section 4.9.10 is meant to place 
requirements on relying parties, not on CAs, which explains much of the 
confusion.

The result is a total rearrangement of Sections 4.9.9 and 4.9.10. This ballot 
empties 4.9.10, moves all of its requirements into 4.9.9, and arranges them 
into three sections:
- A few definitions (which apply only in this section);
- Requirements which apply to OCSP Responders whose URLs are found in the AIA 
OCSP field of certificates; and
- Requirements which apply to all OCSP Responses, regardless of how it was 
queried.
