Which location should I choose?

When choosing a data center to start a subscription, keep in mind the geographic locations of all those attempting to access the server. If low latency is important, then the closer the servers are physically, the better the connection quality is.

Here is a set of IP addresses, one for each data center, to test latency or perform a trace route:

Atlanta
208.52.190.1

Dublin
208.83.1.1

Las Vegas
207.254.73.1
