I think they boasted to be raid proof but aren't such good sysadmins.

Or maybe they could bring it back by switching the DNS of one of their numerous domains to a server still up, but don't really want to/feel like they're done with TPB.

Basically, I think the raid took down their load balancers. So they probably still have servers up in the cloud, but without load balancer as an entry point it's useless.
