As September 20th I think blocking has just got tighter! VPN PPTP port is blocked altogether!! vpn clients like Your-Freedom that provide free services for Iranians don't work anymore! SSL protocol was blocked for several hours yesterday too! strangest of all, I can't connect to TOR either! even by setting alternate bridges! I thought TOR was more resistant to this kind of attack!! (are they blocking any specific ports for that?). this is so frustrating! I really hope Austin would release a public version of Haystack ASAP, we are all looking forward to that!
