I am a Chinese who constantly browse the Internet with VPN. My VPN service is certainly disrupted: for example, the web site of my provider is no longer accessible, and about half of the VPN servers cannot be connected to either. But I can still connect to VPN (I'm using one now). Some of the servers are still accessible, and *PPTP protocol itself is not blocked, at least for the current being.* There is no telling what the Chinese government is going to do next.

Funny, because as a Chinese I use IPv6 to circumvent Chinese government's Great Firewall. I can access YouTube, Facebook and Twitter via IPv6, which are normally restricted by ISP. But of course in the future when IPv6 becomes widespread, GFW will extends to IPv6 networks.

The main reason that the Chinese government "loves" IPv6 is the same as it loves any advanced technology, for in modern history, each revolution in sci-tech changes the power balance of the world, so China must seize every possible chance to surpass other countries. If we can't develop a superior technology, at least we can adopt it quicker than others.

By the way, I always wonder why bittorrent over IPv6 networks is orders of magnitude faster than over IPv4 networks. Is IPv6 inherently faster or just a special case in our school?

Chinese here. Solutions:

• Use VPN.
• If you have IPv6 access (you can use tunneling if your ISP does not have native IPv6), download a hosts file at https://code.google.com/p/ipv6-hosts/source/browse/hosts and replace your system's. This will force ipv6 connections to Google, Youtube, Facebook, Twitter and some other sites. Append .sixxs.org to any other sites blocked. GFW does not censor ipv6 traffic for now, presumably because not many people use it.
• Use GoAgent. It's documented in Chinese so you need help from Chinese to setup. In default mode it is very fast, but compromises secured connections. You can setup https mode by sacrificing speed.

There are many other methods, all slowing down your Internet connection substantially, so I'm not going to recommend here.
