I wonder why. I am not in Korea, but once I had difficulties getting on your site in China. Now everything is fine. What I did on my sites was to get a dedicated IP address. Are you on shared hosting? It seems when another site on a shared IP messes up, all the other sites on that IP get blocked or filtered out. Goodluck resolving this. It can be a real headache. Sorry mate!
