Registrant Information Verification Failure

As a Registrant of a domain name, a new domain registration or changes to the first name, last name or email address of an existing domain name, requires verification of the information within 15 days. Since you failed to verify the Registrant information, this domain name and any other domain name using the same Registrant information no longer resolves. For your domains to operate and resolve normally, resend the verification email to yourself, and complete the verification process.
