Facebook once again has been blocked in China due to Urumqi clashes. The government is keeping checks on all the traffic that comes in and goes out of the country and that travels inside the country. AllFacebook has more to say about the service getting blocked in China. There are lots of proxy sites which you still might use to gain access but China’s government is really strict about it and keeps all the checks and these sites ultimately gets blocked. The best solution here is to use JonDonym Jap. This is one of the best tools that I have ever used to go anonymous.
The JonDonym/AN.ON technology is based on the principle of multiple (layered) encryption, distribution and processing. This procedure does not only protect your internet activities from being observed by third parties (against your access provider, WLAN hackers, advertising services and websites), but also against observation by the individual JonDonym providers themselves (against JonDonym service operators and their billing providers).
