Last week I mentioned the latest chapter in the Chinese government's efforts to seal the country off from the rest of the Internet—and what I considered an out-of-date report in The Guardian about the situation. The Guardian report was based on the palmy-in-retrospect era a few years ago when the government censored attempts to organize protests, but otherwise let people have their say.
No more. From a foreign reader in Shanghai:
The Guardian article you linked to cited some interesting research, but they're pretty out of date, and they missed the point/reality of the firewall pretty badly for an article claiming to tell us the "fascinating truth" about the situation here. ...I've been living in Shanghai for almost two years, so the censorship started tightening not long after I got here. It was ironic because right after I arrived I read a newsletter from the American consulate here saying that the local government was considering lightening the firewall in Shanghai as a "special zone" style experiment, including unblocking Facebook. Obviously, that report was either false or else the plan got shot down by hardliners higher up the food chain.
But things have definitely gotten worse lately. The Guardian didn't mention the self-censorship that most media companies have to go through, but I recently sent a WeChat message to a friend (in English) that was mildly critical of the government. The message didn't go through, and for the first and only time in more than a year of constant use I was booted from the system on all my devices. This is just an anecdote, and it could be a coincidence, but it definitely goes against the "criticism is ok as long as you don't try to mobilize" philosophy.
The other thing they're missing, and that doesn't get discussed enough, is the social engineering part of the Party's censorship project. Just because a website isn't "blocked" doesn't mean they want you to use it. Part of this is their war on Google: many (maybe most) websites these days use Google Fonts. In practice, this means that millions of websites include a call to Google's servers when you try to load their page. I've noticed that this call hangs a lot of the time, causing the page to load excruciatingly slowly. Again, I can't prove this, but I've noticed it with many sites that are completely non-political and technically unblocked.
Even without Google, they throttle their international connections here. I play around a lot with Ping, and as a totally non-scientific example, pinging Baidu without a VPN takes 17ms on average with 0% loss; pinging the Atlantic without a VPN takes 350ms and about 40% loss. With a VPN, both are about 250ms with 0% loss. This is why I often need to use a VPN even for sites like xkcd, which has nothing to do with anything that the Party cares about but which is so slow it doesn't render properly.
The goal of this is obviously to nudge (maybe too gentle a word) people towards the Chinese internet/intranet. I'm sure you had this experience here as well: Youku loads like a dream here, and it's the best streaming video site in the world as far as I'm concerned (and mostly free!). Baidu, QQ Music, WeChat, Taobao ... everything the government wants you to use is fast, free, and for the most part beautifully designed.
One of your earlier posts quoted a businessman in China pointing out that the internet in China just "doesn't work." This isn't quite true. The Chinese part works very, very well ... it's only when you try to access overseas content, no matter how innocuous, that you start tearing your hair out.
Further in this vein: A report from WantChinaTimes.com—which, bear in mind, is based in Taiwan—about foreign-owned businesses finding it harder to do business in China. And a valuable discussion in ChinaFile on "Is Mao Still Dead?" Spoiler: maybe not.
As I've written a million times, I'm overall a big fan of China and hope for its continued emergence. But as I've written almost as often, these past two years of crackdown under hoped-for "reformer" Xi Jinping have been discouraging to put it mildly, and we'll hope that at some point we can look back on them as a nasty phase.
