At first I noticed a few blocks of broken links on some Web pages. Then I started receiving “connection timeout” and “server reset” messages. Access to my favorite places like Facebook, Twitter and YouTube was unsuccessful. Furthermore many food blogs I regularly visit were inaccessible as well. These were not symptoms of a widespread network failure, but rather the result of surfing the Internet from Shanghai. Such was the extent of the “great firewall” of China I encountered during my travel there last fall.
