The dominion nameservers do not exist at all; this is a problem. If a resolver happens to learn that NS set (which is unlikely because the *.tk boxes send minimal responses, but it can still happen), your domain will be dead to those resolvers.

Also, having two entirely different NS sets like this is a violation of DNS specifications. Don't do it.
