Great Firewall of China
Posted: Sat Jul 06, 2024 9:49 am
As is commonly known, many sites and services familiar in the west are absent in China.
These include anything Google: Search, gmail, YouTube, g-Docs....
Also missing are Yahoo, Reuters, BBC, AP, and more.
How's it done? It seems mostly by DNS servers available to users in China; they just don't translate the text url to an IP number.
-Ah, but if you know the IP address, then what? Tried it and it doesn't connect. Easy enough when there is central control over routing.
Let us say, that instead, you try a apps like Baidu (Google replacement), WeChat, DuoYin (TikTok) and are forgetful enough to type a
"trigger" word such as insert your favorite sensitive subject here, etc., the connection is instantly dropped. Without getting to the rights and wrongs, the tech question is how is this done with such a huge volume of traffic?
This paper is old, but show how it works:
VPNs, frequently changed, seem a practical, if temporary solution.
