Around 18:00-18:30, 3/8/2008, Beijing GMT +8:00, Google is blocked by China for about half an hour. It may not be a blocking, but anyway, Google's name server is unavailable for a short period of time. Maybe it's Google's own problem, but in the same time iTunes is not available in China, either. Thus It seems it has something to do with Chinese GFW (Great Firewall).
