Only Chicago right now. We'd like to expand when the economics makes sense (there is a bit of a chicken/egg problem there where we definitely lose some potential sales by not providing the region folks want - but we need sufficient saturation to pay for the new deployment).

My advice if you want to use our service but in a region besides Chicago: use our service and email us the region you'd prefer. In the mean time, the extra 20ms round trip latency probably won't bother you and we'll let you know when we expand in the future (and your voice will help decide where!).
