What do you see when you view the certificate of icloud.com? At this moment, I see this chain: "DigiCert High Assurance EV Root CA" " DigiCert SHA2 Extended Validation Server CA" "www.icloud.com" Valid from "‎07 ‎February ‎2018 01:00:00", sha1 thumbprint: "‎66 de 98 b6 3a 7c 4e eb 0a aa 03 a2 30 57 9e fa 18 e5 c7 fe" I'm interested to see how many different certificates exist as valid and are being used at the same moment for some site so important like this one.
