Server choice & matchmaking

Guides and troubleshooting for problems caused by bad server or region selection, matchmaking failures, host migration, regional throttles and cross-region play settings. Includes how to identify which game server or match host is causing latency or rubber‑banding and step-by-step fixes (change region, force nearest datacenter, adjust account/queue settings). Does not cover home-router tuning, ISP peering, or general PC performance optimizations, which are handled elsewhere. Evidence: traceroutes and server IP mappings, in-game region and datacenter logs, measured ping and jitter to listed datacenters, match timestamps showing host migrations, client/server region configuration screenshots
