While the Megaupload criminal process rumbles on, there’s a controversy emerging around what happens to the 25 petabytes of content uploaded to the service by its users. It’s currently stored on 1,100 servers at Megaupload’s hosting service Carpathia, which says it’s spending $9k a day maintaining the files but hasn’t been paid since its client’s assets were frozen. Now Carpathia says it may have to delete the files, which has spooked lots of people. The Electronic Frontier Foundation wants it preserved so users who stored non-infringing files on Megaupload can get them back. Meanwhile, film industry body the MPAA wants it preserved as evidence for a potential civil lawsuit against Megaupload and its executives.
