Hi folks, China blocked about 80% of the public Tor relays last week: https://blog.torproject.org/blog/tor-partially-blocked-china They're really focused on circumvention tools this week in preparation for their upcoming Oct 1: http://en.wikipedia.org/wiki/National_Day_of_the_People's_Republic_of_China Many bridges are still working fine, though they did block quite a few of them too. Eventually it would be good to shift your Tor relay onto an IP address that isn't blocked. There are two ways that they're doing blocking. One is to filter your whole IP address: no packets get in or out. You can check if this has happened to you by trying to reach baidu.com from your IP address. The other blocking approach is to send TCP reset packets when connections are attempted to your IP:port. That's harder to check. I did a scan last week from inside China, and I've put the result for your IP address up at http://freehaven.net:8081/2009-09-24/<IP> e.g. http://freehaven.net:8081/2009-09-24/128.31.0.34 Note that the above URL includes answers about both known-blocked relays and also known-blocked bridges. It's possible that they'll remove the blocking all by themselves in a few days, once Oct 1 passes. It's also possible they'll do another round of blocking real soon now. Hard to say. So if it's hard for you to get a new IP address, I recommend waiting until at least next week. But if you have plenty to spare (or you're on a cable/DSL system that will give you a new IP address if you just poweroff your cable modem for a while), then now would be a fine time to switch to a new one. Remember that if you're on a multi-homed computer and moving to a non-default IP, you will want to set both Address and OutboundBindAddress in your torrc. Thanks! --Roger
