Understanding China's Great Firewall: Why Twitch Was Blocked and How It Works

Twitch, one of the world's leading video game streaming platforms, has long attracted gamers globally. Recently, it became the latest target of China's internet censorship, with access blocked nationwide.

This followed a surge of Chinese users accessing Twitch for the sole Asian Games stream from Jakarta. As a result, Twitch joined the blacklist alongside giants like Facebook, Twitter, and YouTube—enforced by the infamous "Great Firewall of China." But what exactly is this system, and why does it exist?

What is the Great Firewall of China?

Officially part of China's Golden Shield Project, the Great Firewall is a sophisticated system of internet controls. It blocks websites deemed sensitive, monitors traffic, and prevents access to content critical of the government. Twitch likely faced the block because its live chat features allow unmoderated discussions, potentially exposing users to dissenting views.

Many in China access blocked sites like Facebook or Twitter using VPNs, which mask IP addresses and encrypt traffic to evade detection. However, using VPNs is illegal, and the Great Firewall actively targets popular providers by blocking their IP ranges—not all work reliably.

Tearing Down the Wall: Looking Ahead

With more sites added to the blacklist daily, understanding the Great Firewall—its purpose, mechanisms, and workarounds—is crucial. Do you see similar controls emerging elsewhere? Share your thoughts in the comments.
