Firmina is a cross-regional submarine cable connecting Argentina, United States, Brazil, Uruguay. Its 4 landing points at Las Toninas, Myrtle Beach, Praia Grande, Punta del Este bridge the networks of South America, North America, providing an important path for international data traffic. North-South American cables typically land in Miami or Jacksonville, connecting to Brazil's internet hub in São Paulo — one of the world's largest internet exchange points. GeoCables maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
