Submarine Cable Health Monitor

GeoCables Cable Health Monitor provides real-time monitoring of over 723 submarine fiber optic cables worldwide. Our system continuously measures network latency and detects outages, degradation, and routing anomalies across global undersea infrastructure.

How It Works

We use our own network probes deployed across multiple continents to perform continuous ping and traceroute measurements to landing points of submarine cables. Our anomaly detection engine compares real-time measurements against established baselines to identify potential cable issues including:

Cable breaks and outages causing complete loss of connectivity
Latency degradation indicating cable damage or congestion
Route changes suggesting traffic rerouting around damaged cables
Packet loss increases pointing to equipment or cable issues

Method Validation

Every flagged anomaly is cross-validated two independent ways: against a change in the autonomous-system (AS) routing path at the time of the event, and against whether other probes monitoring the same cable observe the same degradation. Events confirmed across multiple independent probes on the cable are labeled confirmed cable incidents; a latency spike seen by a single probe whose co-monitors stay healthy is reported as a local routing or measurement artifact rather than a cable fault. This dual cross-validation is how GeoCables separates genuine infrastructure events from transient, single-vantage noise. Read the full methodology →

Live Monitoring

Our system performs direct cable health checks every 3 hours using our probes near cable landing points. We measure RTT between endpoints of each cable, track baselines, and alert when latency rises well above each cable's adaptive baseline. Additional city-to-city measurements run every 6 hours from our own probe infrastructure in Minsk (Belarus), Almaty (Kazakhstan), Tbilisi (Georgia), and Jerusalem (Israel).
