Hi Everyone, I'm stuck in a never-ending conference call at work because of significant enterprise-wide outages. These outages have been caused by apparently valid certificates failing to verify. Our investigation has revealed that the AddTrust Root CA certificate expired today but our certificate issuer sold us 2 year certs without checking every cert in the chain of trust was valid until the expiry date of the certs we bought (There was only 1 year remaining on the Root CA cert on the day they sold us a 2 year cert signed with it.) You may wish to check the chains of trust on your certificates... All the best, Paul.
