Unless Wikipedia is wrong, (I never doubt Wikipedia though), "Megaupload is an online Hong Kong–based company established in 2005 that ran a one-click hosting online service of the same name, along with its sister services. The site was shut down by the U.S. Justice Department on January 19, 2012, during an investigation into alleged copyright infringement.[2][3][4], leading to what activist group Anonymous calls 'the single largest Internet attack in its history'."

"The US government has shut down top file hosting service Megaupload and had its founder arrested on suspicion of causing $500 million in lost revenue to content sellers.
The Megaupload sites were managed through an international network of companies, head-quartered in Hong Kong.
Although not a US company and not managed from the US, the fact that it maintained US servers and supplied millions of US visitors with illegal downloads was considered ample legal grounds for the federal government to move against it."
