Although I have a “2 MEG” ADSL connection from Shanghai, I found it especially slow when uploading/downloading changes using Adwords Editor.
All the inbound/outbound internet traffic from China goes through the Great Firewall of China. It’s basically a sophisticated filter that blocks many websites including offensive content.
Before I left Florida, I set up LogMeIn, a remote desktop sharing application which allows me to access my computer in Florida while in Shanghai.
Now, if I want to make a change to my Adwords account, I simply log into my computer at home, make the changes, and upload my account. It’s fast because it’s using my high bandwidth Florida connection.
