Google will from February 2015 stop showing the Green Address Bar for EV certificates that are not logged in a public Certificate Transparency log.
All EV certificates purchased from Servertastic will be automatically published to a public log.
More details about this are available here: Certificate Transparency
The only exception is EV certificates which are installed on internal networks not accessibly from the public internet. If you or your customers have an EV certificate on an internal network then an email will be sent requesting permission to add your certificate to a public CT log. Please be aware this contact may come directly from Geotrust, Thawte or Symantec to the Admin/Tech contact on the order. End customers will not receive any Servertastic branded emails.
