hurmm... just now it seems that i cant login into facebook while my brother is seamlessly playing it beside me on his computer. is kinda weird because i cant even login... then got an idea.. try pinging their website...
tried pinging facebook.com, yeah..no problem with the packet at all..
tried pinging login.facebook.com, wow... no reply at all... it seems that they're using different server just for the authentication since the ip is different that the main one.
