Let’s Encrypt will revoke over 3 million certificates on Wednesday, March 4th, due to a bug in their domain validation and issuance software.
A bug in Let’s Encrypt’s certificate authority (CA) software caused some certificates to not be properly validated through Certificate Authority Authorization (CAA) configured for an associated domain.
