How to prevent traffic from China?

Question

I have set up a test machine (g1 small) in us-west-1c. It has just a node.js web site. There are no known users other than myself doing testing. I can understand that anyone now can hit the web site.

My monthly bill shows non-insignificant traffic Compute Engine Network Internet Egress from Americas to China. As I am still conducting testing, I need not open the web server to China. Is there a way to cut off traffic requests from China, however China is defined? Am I right to assume egress to China is a result of requests coming from China?

Rather I suggest to just WHITELIST your machine(s) from which you can tesy — Sunil Singhal, Sep 03 '17 at 17:37

It sounds like you might be getting crawled by bots...search engine or otherwise. This related question may have some ideas about locking things down on the application layer. And it would be good for the rest of the accidental traffic, too.

You might be getting crawled by bots of search engines. Add followings to your /robots.txt.

User-agent: Baiduspider
Disallow: /
User-agent: Sogou web spider
Disallow: /
User-agent: 360Spider
Disallow: /
User-agent: ChinasoSpider

There are so many search engines in China. You can enter https://www.baidu.com/robots.txt to see more UAs of Chinese search engines' spiders.
