I used CommView to view the network traffic on my NIC. Here are the ip addresses of the data servers for zenfire.
64.202.118.240 - this one had the most traffic
64.202.118.230 - 2nd most
64.202.118.236 - 3rd
64.202.118.132 - 4th
I then used PingPlotter to trace packets. I don't remember if I traced them all or not but the ones I did trace returned "Destination address unreachable". The last hop that was reached was 82ms.
