Gmail Reportedly Has Been Blocked In China 145

An anonymous reader is one of many to point out a report that Gmail has been blocked in China. A years-long war between Google and China that highlights the ideological chasm between the two behemoths has now entered a new phase. On Monday morning, reports confirmed online chatter that Gmail has been fully blocked in China. And transparency advocates say they know exactly what's to blame: China's Great Firewall. "I think the government is just trying to further eliminate Google's presence in China and even weaken its market overseas," an anonymous representative of GreatFire.org told Reuters. "Imagine if Gmail users might not get through to Chinese clients. Many people outside China might be forced to switch away from Gmail."

Gmail Reportedly Has Been Blocked In China

    The article talks about access to gmail accounts, either directly (web) or via POP/SMTP clients. It then has the quote:

    "Imagine if Gmail users might not get through to Chinese clients. Many people outside China might be forced to switch away from Gmail."

    , which would require blocking server to server traffic (and may cause more problems to China than the rest of the world). Is this what's happening or is it just something to "imagine", or a suggestion to the Chinese government on how to hit google harder?

        If you mean the SMTP protocol supports chained delivery routes, then I do not think this is true (at least not used in practice). However, business customers of Gmail (at least) can request that a different SMTP server than Google's be used for outgoing mail, and (of course) anyone using an external mail client can send using any SMTP server they like.

          Wouldn't it be easier to filter outbound packets destined for Gmail's SMTP servers and prevent Chinese email users from sending email to Gmail users? (This is an honest question.)

            I think you mean Google's MX servers (the remote end when sending email through SMTP). If so, in a word, "yes", much easier, assuming users are using SMTP servers based in China. Indeed, you could simply prevent the connections from ever taking place, simulating authentication errors.

        Or simpler still, it could just be Chinese authorities purposefully messing with DNS propagation.

    • I reckon it is more likely to motivate Chinese private businesses to host their mail outside China. Whatever else you might say about Chinese businessmen, they are very good at keeping their eye on the bottom line. The state sector might not be able to do that, but they are less export oriented anyway.

          Chrisq's claim, as I understand it, is that Google would have to negotiate transit with each individual last-mile ISP to make Gmail available to the ISP's customers, or at least available at more than 1999 DSL speeds.

        You might reasonably think that. You'd have it wrong, though.

        The Great Firewall can trivially stop people from (directly) connecting to Google itself, and can stop Google from sending traffic directly to servers in China.

        How, though, does the Great Firewall stop email from going between Google servers in the US
        • The bigger concern is that you may not be able to reach any users of the very popular (and state-supported) Chinese services. If you can't do business with people in China through Gmail (and corporate GMail is a significant portion of GMail), you will switch to a provider who does. Or Google figures out a workaround.

          In other words, it's a real concern, but not one I would lose a tremendous amount of sleep over. I'd much rather worry about Chinese hackers absconding with my data than about the Great Firewall

        • How, though, does the Great Firewall stop email from going between Google servers in the US, and Yahoo/Microsoft/etc servers in the US? Short answer: It doesn't.

          If they wanted to? With DPI, which they already do.

        • I am not saying that it would not be something you could not get around. The the average user sending the average message would be screwed. Not only is the average email unencrypted but it contained a from address, and i imagine mosy outgoing email comes directly from a gmail server, and is not ping ponged around teh world such that the sender is anonymous.

      That isn't how the Internet is meant to work. But yes, they could theoretically block emails from whichever domains or IP addresses they want to, but this is beyond what they have been reported to have done so far.

      To me the question is how does this impact trade and WTO rules and what if any retaliatory steps the US government is going to take against Chinese companies doing business in or trading with the US.

      • but this is beyond what they have been reported to have done so far.

        No its not, they were tampering with connections to google in the past based on what search query you entered and forging RST packets if you searched for "illegal content".

        DPI is the bread and butter of the GFW; Im sort of astonished at how naieve people are about what they actually do.

        • by bigpat ( 158134 )
          The reporting so far is that access to gmail accounts has been blocked, but specifically blocking emails from gmail.com users to other email accounts has not been reported as far as I know. But I was agreeing that they could technically do so.
          • And I would agree that not only are they not doing that, but that they probably wont do it. China's whole MO with the GFW is to subtly punish "deviant" internet users, and reward conformant ones. Blocking email from gmail users would punish both and make their filtering more generally known.

            They tend to prefer things like making gMail or google really spotty, slow, or unreliable so it is obnoxious to use without it being obvious that its actually censorship.

            • I don't know if that is there MO. Last time I was over (and admittedly it has been a while), the GFW was ISP based. Some stuff would work in one place and not another. I think that sometimes we overprescribe evil genius when the answer is just plain old incompetency.

              • They design it to appear sporadic. Generally you have to hit a certain number of "deviations" to trigger a problem, and often things like VPN will work for some short period of time before breaking and bringing your connection to a throttled state.

    • by dAzED1 ( 33635 )
      really? If china blocked all incoming email from google servers, you don't think that might force people outside of china who want to do business with people in china to use email services other than google? Are you /certain/ you know how the internet works?
    • This isn't how the internet works.

      Yes it is. They're blocking *everything* from Gmail, including the SMTP traffic. In other words, people with Gmail can no longer send email to or receive email from people in China. People outside China who need to have email to people in China may very well have to switch away from Gmail.

      • I don't know that that's true. I can still send email from gmail to my stupid @qq address. Of course I have to be on a VPN now in order to access my IMAP servers at Google, which is new these last few days. Google webmail has been down about 90% of the time for the last year, but sometimes used to work late at night.

        This blocking of IMAP (and presumably ActiveSync if Google still uses that, or whatever other proprietary protocol they may use in their various apps) is new.

    China needs to keep up economic growth, or the people who have gotten used to being "middle class" over the last 15 years will not be happy. So, cutting off ways for small and medium-sized importers in other countries to get product info, quotes, arrange for shipping, etc ... not so good.

    And of course, this will also hurt many external alibaba customers.

    What next - forcing people to switch to China's dead Red Flag Linux [theregister.co.uk], just to spite the west?

    • How is GMail necessary to the growth of the middle class? There's 1.3 billion people who can pick from any other email provider. Compared to creating an OS from scratch, creating and running an email service is trivial.

      I thought so too at first - China blocks access to any and all google services. But then I realized that the article (and title) are poorly worded. What China did (in addition to already blocking access to the actual google services) - is to block any email sent from/to anyone with a mailbox at gmail.com. That is to say - as a gmail.com user, you are no longer able to exchange emails with users of various email services based in China.

      That is, in fact, somewhat bigger news - they are breaking an intercommunication capability.

      • Does that affect users of the gmail SMTP server or people who use a @gmail.com address?

        • At least the first one, got a call a few days ago from a relative whose Gmail account in Thunderbird completely stopped working.
          • I'm not sure SMTP is being blocked entirely. I can still send email between QQ and my Gmail and Google Apps hosted accounts. What's *new*, though, is that I can't access the IMAP servers without being on the VPN. Once the mail leaves Google, though, it's arriving at QQ, and once the mail leaves QQ, it ends up on Google's servers. I simply need a VPN to get to Google's servers.

            Yes, Google services (which are primarily web-based or rely on ports 80 and 443) have been mostly blocked for about a year, now, but

      China doesnt use a handful of pf rules, they use a comprehensive array [wikipedia.org] of filtering, DPI, and firewalling techniques. They've been known to actively probe VPN services to determine whether they are allowable, implement real-time updated keyword content filtering, and forge RST packets for any "undesirable" content.

      They are also incredibly proactive about nullifying workarounds; ask the Tor guys [torproject.org] how their efforts with e.g. obfsproxy and obfs2 went. Really good at circumventing the GFW for a year or so until it ended up 100% blocked just like stock OpenVPN.

      Either way its difficult to defend the idea that China intentionally did this

      No, its not, it fits 100% in with their existing (bad) relationship with google.

      when google gladly censors their search results and complies with all local regulations.

      Your information is about 5 years out of date. Ever since the Aurora hacks in 2010, Google has ceased all cooperation with the Chinese government on that front [wikipedia.org], and has ceased filtering on their end. They have in fact on a number of occasions worked to alert users when third party tampering has occurred, which has led to a number of confrontations with the Chinese gov't. Notably, in June of this year, China completely blocked Google [mashable.com] prior to the TIanenmen Square anniversary.

      Google remains a sterling partner of the chinese leadership in their quiet, tacit business participation in what for all intents and purposes amounts to a capitalist dictatorship with a communist logo.

      Except for the part where they are the one major internet company NOT cooperating with them, while Microsoft and Yahoo continue to do so. Hope you dont use Skype [unm.edu] over there.

      • I'm an English teacher in China at the moment, so let me add some observations to your post. The Great Firewall is definitely noticable on any foreign website, as they load much slower than native Chinese websites whereas I didn't notice much difference between American websites, Canadian websites, and European websites when I was still in the U.S. OpenVPN connections are still viable. In fact, the only way that I can get onto the real Internet nowadays is thanks to the volunteers at VPN Gate and SpeedVPN
    • Either way its difficult to defend the idea that China intentionally did this when google gladly censors their search results and complies with all local regulations.

      They apparently stopped doing that a while ago. [blogspot.com]

      “We have decided we are no longer willing to continue censoring our results on Google.cn,” Google wrote in a lengthy blog post. “We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China.”

The same goes for the other tech toys made in China. Lots of people are willing to fork over money for "fair trade" coffee, but don't think twice about where their latest gadget comes from.

    • Apple is part of the US oligarchy. Just like European royalty in the 18th and 19th century, today's oligarchs often have more in common with each other then they do with the people of their own country. That's why nothing is likely to happen with Apple in China.

      If you're going to play the oligarch card, trying to cast primary blame on the peasants/consumers avoids the real issue. There is class warfare going on, but only one side knows it's a war. Right now the peasants are clueless, so they always loose.
