We're going to try it. The pings were that inconsistent. Here's a chart showing some ping data by the various regions and cities. Yes, there are some further conclusiong one can make about this data :)
Notice how the Sydney servers had significantly higher ping times on average. We're addressing that first. We'll be watching for the "long tail" to become shorter, and also that we see lower overall ping times in the new Asia and Oceania regions.
Here are the results of the survey about some of the options for the Asia-Oceania region. The 2 region solution will be the first we will try:
Obviously, the concern now is about critical mass of population. The *much* better* solution will be to have the matchmaker consider ping times. That would be fantastic from a systems management point of view as well - we would be able to just focus on getting servers in as many different locations as possible. Until then, we have to do the best we can with what we've got though.
