Smart Cable Routing
Dijkstra-based routing through real submarine cables and landing points from TeleGeography data. Accurate distance multipliers for land and undersea segments.
In-depth analysis of how internet traffic moves through 703 submarine cable systems, based on real RIPE Atlas measurements from 5 probes worldwide.
Le 3 juin 2026, un séisme de magnitude 4,57 s'est produit à environ 6 km vers le nord-ouest de Kahaluu-Keauhou, Hawaï. Les câbles sous-marins ayant des points d'accostage dans un rayon de 350 km, y compris le Réseau Southern Cross Cable et Honotua, fonctionnent actuellement normalement. Nos mesures de latence indiquent qu'il n'y a eu aucun impact du tremblement de terre sur ces connexions critiques.
1er juin 2026 - GeoCables a connu une journée propre et stable sans anomalies ou alertes actives sur notre réseau. Au cours des dernières 24 heures, nous avons effectué 1852 vérifications de latence/routage sur 517 des 703 câbles sous-marins catalogués, assurant un suivi robuste à grande échelle. L'état général du réseau reste fort, reflétant un environnement opérationnel calme.
Il convient de noter que plusieurs câbles ont montré des variations mineures dans la performance du signal. Par exemple, PGASCOM a résolu une alerte avec une augmentation significative du temps de trajet aller-retour (RTT) de 100%. D'autres câbles comme TIKAL-AMX3 et SPCS/Mistral ont connu des augmentations respectives de 258% et 184%, tandis que ARCOS a vu une augmentation de 171%. Ces fluctuations sont dans la norme du jitter opérationnel et ne montrent pas d'indications significatives d'incidents ou de dommages à l'infrastructure des câbles sous-marins.
L'événement en Indonésie a affecté le fonctionnement des câbles sous-marins, ce qui a entraîné une augmentation des retards. Notre analyse fournit des informations détaillées sur l'état actuel.

Du 17 avril au 7 mai 2026, la latence Tannat entre l'Argentine et le Brésil est passée de 25 ms à 506 ms — vingt fois le plancher physique. Douze alertes, câbles voisins impeccables.
GeoCables a signalé 82 anomalies de latence sur 49 câbles sous-marins en 53 jours. 16 ont franchi notre seuil de haute sévérité. Chaque événement, cartographié.
Le RTT Tbilissi-Aden est de 790 ms — et le chemin passe par Francfort, puis par Starlink, vers le Yémen. Avec les câbles de la mer Rouge hors service à cause du conflit, le satellite est désormais la voie en fonction.
Le RTT Almaty-Tokyo est de 877 ms — 16 fois le minimum orthodromique. La traceroute révèle la route : Kazakhstan-Londres-Singapour-Japon, 21 000 km de fibre pour une ville à 5 400 km.

Dijkstra-based routing through real submarine cables and landing points from TeleGeography data. Accurate distance multipliers for land and undersea segments.
Interactive map showing every cable your data touches — backbone nodes, landing stations, and submarine segments with real geographic coordinates.
Launch real network measurements from probes worldwide. Compare theoretical estimates with actual RTT and hop-by-hop packet journeys with ISP geolocation.
Speed-of-light physics combined with cable distance to estimate latency. See the real-world overhead — how much slower actual routing is vs fiber limits.
Enter cities, IP addresses, or domain names — everything is resolved to coordinates with hosting location identification and optimal cable route.
Traceroute hops enriched with city, country, ISP. Phases auto-detected: local → ISP → CDN → backbone → submarine cable. Visual RTT timelines.
City names, IP addresses, or domains. The system resolves coordinates, identifies countries, and determines whether the route crosses oceans.
A graph algorithm finds the optimal route through landing points and submarine cables with accurate distance multipliers for each segment type.
One click launches RIPE Atlas probes for real ping and traceroute. See actual RTT, identify every router, and find where your packet enters submarine cables.
Validate routing assumptions, estimate latency budgets, troubleshoot unexpected paths.
Understand your ping. Compare the physical speed limit vs reality for any server.
Choose optimal PoP locations based on submarine cable topology and landing proximity.
Teach how the physical internet works. Visualize the gap between light speed and real routing.
Over 500 submarine cable systems span the world's oceans, with a combined length of approximately 1.4 million kilometers — enough to circle the Earth 35 times.
Submarine cables carry over 99% of intercontinental data traffic. Despite what many people think, satellites handle only a tiny fraction of global internet traffic.
Light travels through fiber optic cable at about two-thirds the speed of light in vacuum. A signal from London to New York takes approximately 28 milliseconds one way.
Modern submarine cables are designed to last 25 years. Cables are buried in the seabed near shores and laid directly on the ocean floor in deep water, protected by layers of steel and polyethylene.
The deepest submarine cables reach the abyssal plains at nearly 8,000 meters. At these depths, cables rest on the ocean floor under enormous pressure, beyond the reach of anchors and fishing gear.
Major transoceanic cable projects like 2Africa or PEACE cost over $1 billion. Investment comes from tech giants like Google, Meta, and Microsoft, as well as telecom consortiums.
GeoCables is a research publication on the physical infrastructure of the global internet. We publish in-depth analyses of how data actually travels between countries — which submarine cables are used, what the measured latency is, and why it differs from the theoretical minimum.
Our research is grounded in real RIPE Atlas measurements collected from five probes we operate in Minsk, Almaty, Tbilisi, Jerusalem, and Sevastopol. We trace specific routes across 703 submarine cable systems and 1,900+ landing points cataloged by TeleGeography, then publish what we find.
Light through fiber travels at ~200,000 km/s — about two-thirds the speed of light in vacuum. That sets the theoretical floor for round-trip time. In practice, real RTT is 1.5–4× higher due to routing detours, optical amplifiers, protocol processing, peering between networks, and suboptimal path selection. Our research articles document this overhead on specific routes — measuring it, explaining it, and tracing it back to the cables and networks responsible.
