Brazilian Festoon

Brazilian Festoon is a domestic submarine cable network within Brazil, connecting 14 coastal and island locations including Aracajú, Atafona, Ilhéus, João Pessoa, Macaé, and 9 more. The system provides essential telecommunications infrastructure for communities that would otherwise depend entirely on satellite or microwave links. Submarine cables in this region contribute to a mesh of redundant paths that keep internet traffic flowing even when individual systems are damaged or under maintenance. GeoCables maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
