Echo
MEDIUMEcho is a 14,000km transpacific subsea cable connecting Los Angeles to Singapore and Japan via Guam, co-owned by Google (AS15169) and Meta (AS32934). Ready for service in 2023, Echo supplements the Pacific cable infrastructure for hyperscaler traffic including financial data between US and Asian markets. The cable also serves as an indirect route for London-Singapore traffic via the US. CableAlert monitors Echo via BGP telemetry on AS15169 and AS32934, the same ASNs monitored for MAREA and Grace Hopper — making Google and Meta ASN anomalies relevant across multiple corridors simultaneously.
