In order to ensure a maximum security for developers, Google Registry has decided that any .NEW domain name had to be secured with a SSL certificate,
In practice, this means that you will have 100 days to install a SSL certificate on your .NEW domain name. As long as you do not have one, the domain name will not be serviceable, and will be locked or deleted after 100 days. This means you cannot buy a .NEW domain name defensively (in order to prevent other people from registering the domain name you're interested in).
If you are interested in buying one right now, here is our SSL Certificate Offers.
