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!).
It is more like we provide you a network interface that, instead of being plugged into your modem for Comcast/AT&T/etc, it's plugged into a datacenter.
You get a public static IPv4/IPv6 connection with Reverse DNS - just located somewhere else.
Making your machine publicly routable is the primary use case (e.g., for email, web, whatever you want if you have trouble with NAT/CGNAT or simply don't want your home IP associated with the service), but it also encrypts your traffic between your PC and our datacenter such that your ISP can't snoop - which is not to say we're a good privacy solution - that is not what our product is designed to do.
