Wow...I have the exact same problem:
1. Cant run the client..(Server undergoing inspection blah blah blah)
2. I cant access
http://www.silkroadonline.net (page cannot be displayed)
3. Cant Change password on Joymax portal ( email verification page not displaying properly)
PS I also have not changed any configuration on my computer, nor installed any new program
I experienced this problem when i have to forcibly exit SRO due to no response.... NOT LAG cause other players are moving around me and talking to me etc... When i tried to log back in, I cant execute SRO anymore
