Is Jabber accessible from China?

[belmondo3]

• Just curious, if they can jump over the GFW?
  
  It's harder to block because of decentralized nature of XMPP/TLS, but I've never had any Chinese mentioning Jabber as a mean of conversation.
  
  
• I'm in China and can access many XMPP servers, e.g. xmpp.jp, swissjabber.ch, chinwag.im, yax.im, disroot.org, member.fsf.org.
  
  
• • Thank you for sharing that with me.
    
  • Interesting! Do you, guys, have internal CN-net darknets? I mean, p2p such as Freenet/Zeronet/i2p in your national segment. Havent heard of, but they should exist.
  
  
  
• From what I understand about China's GFW, and I am American so no direct experience, it'll work at the beginning if you use TLS. Maybe not STARTTLS?
  
  However, I do know that all VPNs will eventually stop working, forcing you to switch IP or protocol - the GFW has some basic machine learning. If all you do is connect to a specific IP, it'll start throttling connections to said address. It may do the same if it can't scrutinize the encrypted Jabber connection.
  
  The bigger issue is that Jabber is still more complex to set up securely. That's probably why it doesn't have as much mindshare. Given that reputation, and the state of clients across platforms not all implementing the same features (not even equally well), it's harder to convince someone to deal with all of the headaches involved.
  
  
• I actually had a plane get delayed in Shanghai, and I had no phone plan so the internet was my only option for communication back to the US. Couldn't use Facebook or Instagram. Forget Gmail, because even the Google homepage couldn't be accessed there. Hotmail said it delivered, but I found out the message didn't get received until about 3 weeks AFTER I arrived back in the US. Jabber was the only thing that DID actually work.

Для комуняк виникає те тільки технічна проблема, яку очікують пересічні інженери, а організаційна, з одного боку, і соціальна, з іншого, бо навіть кожний дурень з червоними очима може підняти власний сервер джаберу. Треба докласти великих зусиль, щоби відстежити кожного з натовпу. Децентралізація рулить!

Telegram у рашці поки рятують руки із сраки, але його смерть, принаймні там, це питання часу, якщо звісно там не впаде держава.
