The recent congestion is caused by the price reducing of ISPs demanded by the government. A lot of customers upgraded their bandwidth without paying additional money. This makes the already busy cables out of bandwidth.

Back to your question, the answer is YES, use a proxy, which is less expensive, or buy a dedicated private virtual line from a Chinese ISP, which is more stable.

You can setup a fast proxy by carefully selecting the routing path. Nowadays, the CN2 cable (http://www.ctamericas.com/content.asp?pl=627&sl=637&contenti...) is a good choice.
