Anycast is the proper way to do this. No geolocation required, just dynamic routing protocols optimizing for shortest path.
- draga79 2y agoSure, but Anycast requires specific investments, ASN, IP blocks, etc. This solution can be implemented using cheap VPSes in a few minutes.
- _cenw 2y agoNot to mention that Anycast and TCP can have some fun edge cases for users with chaotic routing and you also need to figure out how to do sticky L4 sessions / forwarding, which can be hell to debug. (Or you could just ignore those users when they complain, PlayFab sure does.)
- otabdeveloper4 2y agoThere's no such thing as "anycast". For IPv4 there is only BGP. And BGP is not viable for a rented server and IP address, unlike running a DNS server.
