I was thinking the same thing today! Georgia holds a big percentage of the network right now. This is centralization, not the fact that there are 6k nodes. We need to focus on the important things!
Its not easy to run a node when it gets DDOSed within the hour.
Mine has been up and chugging along for ages on a home internet connection(200/15), and it's XT too, which seems to get the brunt of the DDoS attacks lately.
