I really appreciate your immediate response.

My home has been working since last night(http://youngsam.com)when I

tried to acces by another computer.. Right now,by this computer I can 
reach 1,2,3,4,5 th server of  byus.net but I can't reach 6,7,8 th 
server...
Is this problem due to my local network? or Byus Server system?

Thank you again.
