Looks like Malaysian can no longer download files from popular file sharing sites any longer..such as megaupload, fileserve, depositfile, filestube, etc. Don't know why suddenly the government decided to do this even though the United States for its strict anti-piracy laws did not implement such laws.
P.S , there is always way to by pass it. Just google "proxy server" , "how bypass DNS block", "how to bypass IP block".
Hence a group of international hackers are planning to target the government's website portal which i think will likely be a piece of cake to hack since security has never been emphasized strongly in Bolehland. (where you can spend millions just to create a simple website)
