My ping tests are always a minimum of 100 times. If you look at my separate post with my traceroutes and ping results I was doing 1000 pings as a test.
One thing I'm curious of is other people's traceroutes. I want to know if the ISPs such as Mediacom and Pipex are going through a Cox router to get to Asianetcom. Someone made a good point that Cox could be leasing bandwidth to these providers (it's a common thing) and if they have to hit a Cox router to go from the USA to Japan, we can't rule out that the ISP isn't totally at fault.
