We believe the Chinese authorities may be stepping up their internet security for the up coming Party Congress on 8th Nov, and may have created a temporary firewall blocking some external internet traffic. We believe this is aimed at "preventing major incidents threatening national security and social stability". We fully expect the level of security to return to normal after the party Congress. If you live in China and have previously had a good connection that has now failed, it is most likely due to the current heightened political sensitivity. We fully expect the internet in China to return to it's normal level of security soon after the Party Congress.
