Thanks for this tool. It was extremely helpful in trying to find the best locations for data-centers across the world. Who knew, that the presence in New York, London, and Singapore alone is enough to be within 100ms reach for 80% of the world's population.

Cool. I don't think the 3 decimal places are significant.
