Chinese authorities began blocking the intermediate nodes and servers, directory services on the basis of the Tor anonymizing their IP addresses. In the columns of Tor's blog can be read that the "great firewall" (GFW) is blocking communication with about 80% of the Tor node. Author of note also admitted that it was expected this turn of events.

Already in the middle of last year, China blocked Tor website. Therefore, the operator of the website and its creators tried to be the protection of the new Tor servers, to prevent the Chinese authorities to get into the list of public nodes - the intention is apparently failed.

Although the establishment of an anonymous connection is still possible using the remaining 20% of the nodes, but such an operation takes a long time. Author of this blog entry advises users that you run a Tor private goals (so-called bridge relays) if they want to help Chinese colleagues. This kind of goals do not appear on public lists, and thus difficult to find and block.
