2020上外网


We begin with a short summary of how we got to where we are today. The Great Firewall  began operation in 2003. Early methods of censorship included Internet Protocol (IP) blocking, Domain Name System (DNS) poisoning, and the malicious insertion of Transmission Control Protocol (TCP) resets. Tor was blocked in 2009, and public obfs4 bridges were blocked a few months after their introduction. OpenVPN was blocked in 2013.


This leaves open the following possibilities for bypassing the G firewall  in 2020:
The original Shadowsocks (SS) is still maintained. Because of their icons, SS are sometimes referred to as paper airplanes (纸飞机). At the very top of the market are services who lease an international private leased circuit (IPLC).International access points are provided here.

Or if you want to try v2ray, go v2cloud.

Users at major universities have freer access to the rest of the world through the China Education and Research Network (中国教育和科研计算机网). IPv6 often works best.
