Since DNSSEC makes the Internet more secure, why doesn't everyone use it?
Implementing DNSSEC across the Internet is a bit like world peace: Everyone realizes that it's a great idea, but implementation requires effort, consensus, and expenses (often significant) world-wide.
The Internet-wide implementation is moving steadily forward, one domain name extension and its registry at a time. As each extension becomes DNSSEC-aware, we'll be there to support the effort for domain names registered through us.
