For CME we colocate in aurora with CME but we also colocate in 350 e cermak for ICE and CME, there we use telx. Cannot provide pricing as we lease cages and the price is split across many groups but we set up all the servers and switches.
Not sure if I get your question right, but just use the commandline tool ping. I'm on Linux, but it's the same on many platforms.
can you comment on the general latency from the 350 E Cermak to Aurora CME, I think they are calling it bulk transport whatever that means.
The ICE servers are in Chicago at 350 cermac. If you are manual trading, there is not much benefit. But if you are doing algo or automated trading it would be huge because you'd be able to reach to price movements and your own order status much faster and also help avoid over fills if your algo does a lot of order modifications.
I mentioned that latency on page 2, 300-500 microseconds one way for fiber connection from building to building not including the exchange systems and network. I'll add that it's about 190 microseconds via microwave/millimeter wave. Never heard of bulk transport, it must just be some marketing term for a shared connection.
