Understanding censorship

Every once in awhile something happens to my internet connection at home... Either it loses connection completely or I end up only able to access communist chinese websites. The latter happened yesterday, and at first I thought I was only able to access websites within China, but I discovered I could access the PRC's embassy website in the US also. I find the whole idea of goverment censorship replusive, and in the case of the censorship here it shows the communist goverment's weakness. Here's a great article about this here.
