Carpathia Hosting says it shouldn't have to heft costs of preserving MegaUpload's data, but U.S. attorney suggests managers should have predicted that partnering with a pirate site would be expensive. ALEXANDRIA, Va.--Carpathia Hosting had plenty of reason to know that their MegaUpload gravy train would roar off the tracks one day, according to a lawyer representing the U.S. government. Ever since January, when the U.S. Department of Justice filed criminal copyright charges against MegaUpload, one of the world's most popular cyberlocker services, the private firm that hosted MegaUpload's servers has preserved user data on its own dime. During a hearing in U.S. District Court for the Eastern District of Virginia, the company told the judge yesterday that the U.S. government should pick up the tab. Jay Prabhu, the lawyer representing the U.S. Attorney's office, doesn't think that's fair. He told the court that if the cost of doing business with MegaUpload has gone up, Carpathia's added expenses shouldn't be thrust onto taxpayers. Later, Prabhu made several comments about Carpathia that for the first time in the case suggested someone other than MegaUpload's managers may bear some responsibility. More...
