There's a huge thread on GBAtemp about it. There was one good point, why not have a backup server? But, how do you make a backup DNS server?
It would be easy to point it to one server, that is a proxy to the other two servers. Use some free DNS, like what your registrar uses.
Read more of it on my phone while shitting on the Jonny. Somebody on their Facebook apparently said the domains were seized, and possibly somebody was arrested. Didn't click the link, they copy and pasted it on the forum.
That's funny if true. That's what happens when you sell piracy. They may be who runs the paid piracy site. That domain is on hold too.
