I'm from south korea, and using KT telecom now.
for exemple, hk server traceroute:

 13   338 ms   337 ms   338 ms  tserv2.hkg1.he.net [216.218.221.6]
in this, my packet first cross the Pacific once to usa,(CA) and then visit LA datacenter, come back over the pacific to tyoko, then goes to Hong Kong. and somehow it spent about 50ms in it.
Just why?

Possibly because of lacking of mutual perring points.
