I read on an Italian blog that MegaUpload, MegaVideo and family are now closed. It was worth 175 million dollars and ranked as the 13th most visited website in the World.
Here is the FBI press release website (which is currently veeeery slow).
The Internet counts now hundreds and hundreds of websites offering similar services. This is the first, but not the last and therefore a clear evidence that we are going towards the end of the Internet anarchy.
By the way, I had a premium activated not long ago. Puff, vanished.

As matter of fact, the following websites are now blocked: justice.gov, universalmusic.com e riaa.com
