Circumventing the Chinese Firewall

When you are trying to access western websites from within China, you will find they are very slow loading and in some cases just don't load at all. The main reason for this slow speed and unreliability is that all your network traffic is being routed through government servers.

Overall, the Internet is slowed down because every bit of information has to pass through these servers that do the filtering. These servers look for flagged keywords and/or phrases such as "communism", "government" or "Tiananmen Square". They also check to see if you are attempting to access a blacklisted website, and if so, the connection is interrupted and your left with an error page.

This process can dramatically slow down access to websites that are outside of china. For the average foreign user in China, this can be pretty frustrating. But for a foreign enterprise operating in China, the effects can be much worse. If your company relies on the internet for communications like most do, then this can cause complications between you, your headquarters and clients. If the internet is an integral part of your business e.g. a web development company, then this could seriously impede your operations.

The solution, a proxy. You have heard of proxies, they are complicated to setup and not very convenient right? Wrong.

There are many proxy providers out there, some are free and some you must pay for to use their services. Many providers have a free service that are decent speeds and have a number of servers around the world, many of which can be used to find the one that provides you with the best speed. There are also many paid proxies, which give you access to greater speeds and a range of other features, such as multiple connections etc.

I have used a free proxy since I arrived in China, it has allowed me to play my favorite MMORPGS (EVE and WOW) and view all the websites I've wanted to. The only draw back to using a free service is that you are disconnected after a few hours or so, this is not a problem as you can easily press reconnect.

For a corporate user, the paid options would be of little consequence when compared with the amount of "freedom" you are getting. Your team can now access any website, know for sure that all communications are getting through and are able to develop freely using the internet.

Just how it should be.
