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 700 submarine cable systems, based on real RIPE Atlas measurements from 5 probes worldwide.
Наш монитор показывает, что пакет из Минска в Острова Кука идёт в среднем 507 мс — через Беларусь, Россию, Австрию, США, Французскую Полинезию и, наконец, Раротонгу. Вот что трассировка говорит нам о реальной маршрутизации интернета.
14 апреля 2026 года RTT между Сайпаном и Гуамом вырос в 13 раз на подходе Cat 5 тайфуна Sinlaku. Кабель Mariana-Guam был цел — упал локальный BGP-пиринг, и трафик ушёл в крюк 12 000 км через Лос-Анджелес. Разбор по RIPE Atlas и BGP.
Maroc Telecom владеет подводным кабелем длиной 8600 км, соединяющим Касабланку с четырьмя странами Западной Африки. Реальная трасса RIPE Atlas: Касабланка → Либревиль за 86 мс, 1,025x от физического пола.
Семь подводных кабельных станций приземления на двух побережьях Ирана, но глобальные транзиты обходят страну стороной. Трассы RIPE Atlas показывают: Иран-Кувейт идёт через Франкфурт и Милан, 175 мс на 250 км пути.
В Индонезии 143 точки выхода подводных кабелей и 72 кабеля — 42 внутренних и 30 международных. Как Palapa Ring, мегахаб Батам и инвестиции Big Tech соединяют 17 000 островов с миром.
В Японии 70 станций выхода подводных кабелей и более 50 кабелей. Наши данные: 18 мс до Кореи, 106 мс через Тихий океан, 300+ мс из Европы. Шесть алертов за 30 дней, все саморазрешающиеся.
Измерено с четырёх проб RIPE Atlas к четырём реальным тунисским IP 12 апреля 2026: медиана RTT 70 мс, три из четырёх путей идут через итальянский Sparkle. Почему шесть кабелей Туниса достигаются через один — и что меняет Medusa 2026.
11 апреля 2026 пакет от Минска до Островов Кука шёл 1969 мс. Восемь дней измерений показывают паттерн перегрузки на кабеле Manatua, который наш монитор не зафиксировал — потому что проблема за landing point, внутри единственной сети на 17 500 жителей пятнадцати островов.

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 700 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.
