GeoGuesser, powered by the Google Maps API, generates a likely location of the user. It finds the midpoint between the 2 datacenters and draws 2 circles that signify his radius.
And with SS7 they can get even more precise location, and you can’t really hide from that if you want to use a phone with a phone number, what is the point. This is an interesting way of attack, noone really thought about this before, but it’s not “oh-my-god everyone can be tracked via signal”. I guess the closest server doesn’t even selected via geographical distance, but much more depends on network infrastructure of your location, so Google Maps API can’t really help here.
And again any VPN could defend against this, so if you want to hide which country you are in currently, it should be the 0th step to use a VPN.

Does everyone have access to tracking which stations send the phone signal in the SS7 network?
Yes, anyone can buy access.
