China just cut off (almost) all external Internet access
Will update this post if things change
Update 11:57: skype seems to work for now. Might just only be the web. Yahoo and Msn messengers don't work though
Update 12:07: seems that data is being sent, but nothing comes back. Also, wsj articles load, but not any assets (css, js, images)
Update 12:20: portions of the 3rd ring road in Beijing are being closed. One of the largest "city highways" in beijing.. This is scary, hopefully unrelated
Update: 13:09: looks like everything is back to normal. Only Facebook and such websites still being blocked. phew
Additional info: yesterday text messages (SMS) containing either "Bo Xilai" or "bxl" were rejected. Apparently everything has to do with this thing: http://online.wsj.com/article/SB10001424052702304444604577337951998961744.html?mod=WSJAsia_hpp_LEFTTopStories
I heard tanks were patrolling streets in Beijing just 2 weeks ago.
It could have just been a glitch and nothing planned, but I agree with the poster that these things should be taken seriously (at least by those of us in Beijing).
(My point is that if they tell you you're getting unfiltered Internet in the U.S., they're lying.)
