Uploaded.to, one of the most popular file-hosting sites in the Internet, has closed its doors to US visitors.

The move is most likely a response to the FBI crackdown on MegaUpload two days ago.

US visitors of Uploaded.to currently get the following message.

“Not Available: Our service is currently unavailable in your country. Sorry about that.”

The site has yet to release an official statement on the “block.” Whether it’s permanent, and the alleged relation to the MegaUpload raids and arrests is unknown at this point.

Uploaded.to’s decision is just one of the many changes the major cyberlockers have made during the past days. More on that later.
