Revocation log
Every certificate we have revoked, by id, with the reason category and the date. Entries are permanent.
Revocation means we no longer stand behind a certificate we issued. The four situations that lead to it are set out in the terms, and the verify page for a revoked certificate says the same thing this log does. Withdrawal after a refund is a separate matter and never appears here.
No certificates have been revoked.
If that changes, the certificate id, the reason category, and the date will be listed here.
Anyone can check a certificate by opening its verify link, with no account. A revoked one shows a notice in place of its grade.
