Submission + - DigiCert Revoking Certs with Less Than 24 Hours Notice (digicert.com)
jdastrup writes: Due to a mistake going back years that has recently been discovered, DigiCert is required by the CABF to revoke any certificate that used the improper Domain Control Validation (DCV) CNAME record in 24 hours. This could literally be thousands of SSL certs. This could take a lot of time and potentially cause outages worldwide starting July 30 at 19:30 UTC. Be prepared for a long night of cert renewals. DigiCert support line is completely jammed.
