Tor and almost any website mentioning or hosting it is blocked, on top of that my experience with Tor is that it is no longer usable.
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.
