CA Root expired on 30 May 2020
Honestly, certificates should never expire or should expire daily. If certificate revocation works then its pointless to have expiring certs. Its just a mechanism for CAs to seek rent.<p>If certificate revocation doesnt work then certs need to expire super frequently to limit potential damage if compromised.<p>A certificate that expires in 20 years does absolutely nothing for security compared to a certificate that never expires. Odds are that in 20 years the crypto will need to be updated anyways, effectively revoking the certificate.
