The Great Firewall of China (GFW) experienced the largest leak of internal documents in its history on Thursday September 11, 2025. Over 500 GB of source code, work logs, and internal communication records were leaked, revealing details of the GFW's research, development, and operations.

There was a massive leak of technical documents and source code from the great firewall project in the PRC on the 11th. Seems interesting.
