Submarine Cables

Submarine Cable Fault Tracker

A live world map that separates Confirmed incidents backed by published reports from Suspected public-network anomalies. A named cable turns red only when report evidence identifies it; dashed amber candidates remain unconfirmed. Network recovery never means the physical cable was repaired.

Click a cable — or an event card — to inspect the underlying evidence chain and fly the map to the affected system. Drag the timeline to replay recent history. Tap the legend to filter by status.

Submarine Cable Fault Tracker

Live world map separating Confirmed incidents backed by published reports from Suspected public-network anomalies. Network recovery is tracked separately from physical repair.

Inputs

  • None — interactive map of all known submarine cables

Outputs

  • Named cables turn red only for Confirmed report evidence; candidate cables use a dashed amber Suspected overlay
  • Click-through evidence chain: published-source links, traffic signals, and measurement details
  • Separate network-recovery and physical-repair states
  • Timeline scrubber to replay the last 5 years

Use Cases

  • First-look situational awareness when a regional outage is reported
  • Pre-NOTAM check before a planned maintenance window in a region with active faults
  • Explaining cable health to non-engineering stakeholders

Data Sources

  • TeleGeography submarinecablemap.com (cable geometry)
  • Cloudflare Radar (country traffic anomaly)
  • IODA / Georgia Tech (country signal cross-check)
  • GDELT DOC 2.0 API (fault news discovery)
  • Bing News RSS (fault keyword search query)
  • DCD Subsea Infrastructure filtered RSS (https://www.datacenterdynamics.com/en/rss/?term=subsea-infrastructure)
  • SubTel Forum global RSS (https://subtelforum.com/feed/)
  • SubTel Forum Cable Faults & Maintenance category RSS (https://subtelforum.com/category/cable-faults-maintenance/feed/)

Limitations

  • TeleGeography geometries are illustrative, not real routes — fault marker is regional, not precise
  • Public-network anomalies can have non-cable causes such as DDoS, blackouts, routing changes, or policy events
  • Measurements alone never confirm a physical cable fault or select a unique cable from a candidate group
  • Network recovery can result from rerouting and is not proof of physical repair; repair states require explicit published evidence
