Here's a link to a very interesting article I read today. It's about the Chinese Internet being disrupted. Ok, I know this is normal. But what I didn't know is that in some universities, there are Internet connections that are not blocked by the great firewall. They made an interesting point, saying that The Chinese government realized the need for an intellectual elite, and therefore allows many university students the ability to surf "the western Internet".
However, just yesterday many universities all over the countries experience problems with their un-firewalled Internet. Google and Gmail wasn't working.
It also mentioned something about hitting "critical mass" for the amount of blocked web sites requested.
Anyway, I won't recite the article, you can read it HERE.
It's pretty long though. If you're not interested, I pretty much summarized it.
