SUMMARY :

Arma Reforger, server region assignment appears to be derived from the nearest ping server. There is no ping server located in Africa / South Africa, so servers physically hosted in and around South Africa are assigned to the nearest reachable server in my case (And another SA Servers) Singapore.
A server running in Johannesburg with a real-world latency of +-20 ms for local players is presented in the server browser as a bad latancy server with 400+ Ping. South African players filtering or sorting by region/ping never see it, and instead see European servers (~180-220 ms) as their "best" option.

IMPACT :

1. South Africa has an active Arma Reforger community but effectively zero discoverable low-ping servers.

2. Anyone who does host locally is invisible to the players who would benefit most, which discourages local hosting entirely, a self-reinforcing loop that keeps the region empty.

3. Players default to EU servers at 180-220 ms, which materially degrades gameplay in a game where hit registration and vehicle handling are latency-sensitive.
