Hi Kano-san, thanks for updating the info.  Did you intentionally disable ping to "sg.kano.is"?  When i try to ping, it gives me a timeout but nonetheless, tracetcp to port 3333 gives me 40ms which still looks very good compared to jp which is 50ms for me!  Awesome!  Will give the SG a try, but just wanted to give you heads up that icmp for sg node is blocked... or if you intentionally did this, no worries.  Just checking out as to some might not know how to confirm connection.
