Certificate Transparency means that the CA that issued the certificate
also published it using a Google-promoted protocol to provide
"Transparency" for the certificate issuing industry, at the cost of
customer privacy.

Chrome Browser now (or soon) punishes websites that whose certificate
was not published that way, making it a relevant test for web server
operators wanting to check that everything will work in all browsers.
