A number of CDNs use tools like the DNS server/query source to identify where the clients are. If they are all using a centralized DNS server, some providers will classify you as in one area vs another. Consider using a different DNS query-source for east coast vs west coast users. Consider using tools like ECS (EDNS0-Client-Subnet) if possible to provide hints to the various CDNs/Geolocation folks. If you’re aware of a specific mis-charachtherisation, consider posting the relevant DNS server information or IP ranges involved. If you don’t know how to find your DNS server query-source, a tool like this: https://cmdns.dev.dns-oarc.net/ Will help you find the information easily. - Jared
