London ↔ Tokyo

JUPITER is a 14,500km transpacific subsea cable connecting Los Angeles to multiple landing points in Japan, ready for service in 2020. The cable is owned by a consortium including KDDI (AS2516), NTT (AS2914), Meta (AS32934) and PCCW Global (AS3491). JUPITER is a primary carrier of financial data on the US-Japan corridor, used by trading firms running Pacific equity arbitrage strategies. CableAlert monitors JUPITER via BGP telemetry on the KDDI, NTT and Meta ASNs, with RIPE Atlas latency probes measuring the London-Tokyo end-to-end corridor.
