Initial reaction from one of the main admins was that if in 12 hours there had been no news they'd nuke the servers, seems like they're not gonna do it anymore. Many domains registered by one admin were seized at the same time, so might not even be aimed at the tracker. Waiting for more news.

Update: Looks like the DNS registrar itself was the one that went down and took lots of sites with it, TorrentFreak article: 100s of Pirate Sites Go Dark as .TV Domains Placed on ServerHold - TorrentFreak
