What services do people use to proxy around it? Just curious.
First users were forced to use a relay, then relay IP's started getting banned, and now I think that the government has found some method to prevent connections to the Tor network completely (I'm not sure how).
Slowly but surely the screws are being tightened, more and more of the western net is becoming unavailable. I guess already 30-35% of all sites linked to on HN are blocked.
So if it does get blocked its not for long.
I wish I could help you with more specific information off the top of my head, but I fortunately don't have to use relays. I am willing to do some research and share the results here if you like.
