The video is phase one of #OpGlobalBlackout. They do recognize that MegaUpload contained copyrighted content, but say that the take down was not about copyrighted materials. Anonymous demands that MegaUpload be reinstated within 72 hours.
Anonymous claims that they have gained access to the servers for the United Nations, PlayStation Network, Xbox Live, US Bank, Capital One, Chase Bank, Twitter, Facebook and YouTube. If their demands are not met, they will take down all of these servers.
Many are saying this is a fake video posted without any Anonymous backing. Currently AnonOps is only refereing #OpMegaupload and not #OpGlobalBlackout. For now, we will move this to rumor and will remove this once we have confirmation that it is fake.
