I know there are a lot of sites that one can't access from Nepal, especially those which the current Nepali government thinks are on the other end of political spectrum. Well, you can use Google as proxy which actually is pretty fast compared to some other proxies people may have been using, just replace "http://insn.org" with the site you want to access.
