## Appendix A - Suggested locations of probe clients and front-end servers

For convenience, we offer a catalog of approximate locations, denoted by latitude and longitude, for each of the probing clients. This list is organized in alignment with the list of probe clients (*list 2*). The data has been sourced from [MaxMind's GeoIP2 database](https://www.maxmind.com/en/geoip2-databases), and although it is claimed to possess an accuracy of 1000 km, a validation through [Google Maps](https://www.google.com/maps) suggests that these coordinates do indeed correspond to their respective state-level regions, albeit with potential minor inaccuracies.
