Earlier this year we announced our intent to provide certificate revocation information exclusively via Certificate Revocation Lists (CRLs), ending support for providing certificate revocation information via the Online Certificate Status Protocol (OCSP).
In today’s blog post, we’re announcing a timeline for ending OCSP services next year.
Websites and people who visit them will not be affected by this change, but some non-browser software might be. Action will be required for the very small percentage of our subscribers who have manually configured their ACME client to request certificates with the OCSP Must Staple Extension.
Read the full blog post to learn more about why we’re making this change and, if you’re one of those who may be affected, the actions you will need to take before next May.
