The Quiet Map: Watching the Internet of Three Billion People

At this moment, nearly the entire internet is functioning seamlessly. On our outage map, 246 of the 247 networks under active observation are green — operating normally. One is experiencing minor degradation. No regions are offline. For the more than three billion people relying on the providers we monitor, connectivity is simply there, as it should be. This global stability is one of the most underappreciated aspects of modern life — and it is precisely what our system is designed to monitor.

We tend to notice the internet only when it falters. A video call freezes, a country trends on social media due to silence, or a bank's app times out — and for a brief period, connectivity becomes newsworthy. The rest of the time, the vast network operates invisibly. A monitoring map transforms this invisibility into visibility: it remains predominantly green, ensuring that the moment it isn't, someone is alerted.

Three billion connections, one map

GeoCables actively tracks the real-time health of 1,011 of the world's largest internet providers across 238 countries and territories — networks that collectively serve over three billion users. These are the critical infrastructures powering the modern world. Our outage view monitors major players like Reliance Jio, with approximately 294 million subscribers in India; China Telecom's backbone, serving over 210 million; Bharti Airtel, China Mobile, China Unicom, and MTN in Nigeria. When one of these networks experiences issues, tens of millions of users feel the impact almost instantly.

For each network, we maintain a baseline expectation — a benchmark of how much of it should be reachable at any given time, derived from its recent performance. Every hour, we compare live data against this baseline using public measurement signals: active pings, routing announcements that confirm a network's existence, and broader reachability telemetry. If the live performance dips significantly below the baseline, the pixel shifts from green to amber to red, and a classifier determines the likely cause.

How you watch a planet

Monitoring every network on Earth is impractical — there are tens of thousands — so we focus on those that serve the largest populations. For each country, we track its most significant providers by subscriber base, keeping them under continuous observation. This approach enables 1,011 networks to represent the connectivity of over three billion users. The map prioritizes human impact over infrastructure scale, as outages matter most in terms of the people they affect.

The raw data comes from public internet-measurement infrastructure, primarily IODA (Internet Outage Detection and Analysis), a project at Georgia Tech. IODA integrates active probing, global routing data, and background traffic telemetry into a unified reachability score. We continuously pull these signals, update each network's baseline based on its recent behavior, and apply a classifier to identify causes. The result is a dynamic, real-time view where a continent's worth of measurements condenses into one clear color per network: green, amber, or red.

Why most outages are invisible

The paradox of a robust network is that most failures are imperceptible to users. The internet functions as a mesh, and a healthy mesh reroutes traffic around disruptions. When a core link fails, traffic takes an alternate path, resulting in only a slight increase in latency. This resilience allows the global cable network to absorb a severed cable without most users noticing. Outages that do affect users occur when no alternate path exists — such as a single regional link, a sole power grid, or a critical decision point.

This redundancy explains why a map representing three billion users remains predominantly green. Issues arise constantly, but redundancy mitigates most of them before they escalate into outages. The map's purpose is to capture the rare instances where redundancy fails.

What "normal" actually looks like

Zooming into any typical week reveals not catastrophes but fluctuations. In the first week of June 2026, the most significant country-level dip GeoCables recorded was in Liberia, where reachability dropped approximately 21% below baseline on the 7th before recovering — a disruption, not a blackout. Yemen and Burkina Faso experienced smaller dips of around 12% on the same day. These fluctuations represent the texture of normalcy: brief, shallow, and self-correcting variations that never escalate into national-level events. Understanding these patterns helps distinguish between a network's routine behavior and genuine distress.

The shapes of a real outage

When a fluctuation deepens into a true outage, it typically falls into one of several categories, each leaving a distinct signature:

• Power and last-mile — A grid failure or a disruption in the local access network. Reachability declines in affected areas, often following a daily rhythm as backup generators and batteries deplete.
• Routing and BGP — A network ceases announcing itself or announces incorrect routes. The drop is immediate and total for the affected prefixes, visible in routing tables before pings fail.
• Submarine cable faults — A coastal or island nation loses a significant portion of its capacity. Traffic reroutes where possible, leaving the remaining paths congested and slower.
• Deliberate shutdowns — A government mandates providers to disconnect. This creates the most distinct signature: a sharp, synchronized drop across all networks in a country, often tied to elections, exams, or unrest.

The red pixel that matters

The value of a monitoring map lies in the rare moments when it is not quiet. National internet shutdowns have become a common tool of control, with hundreds of deliberate blackouts occurring annually. Submarine cable disruptions, such as those in the Red Sea in early 2024, have had continent-wide ripple effects. These are the events our system is designed to detect — and the critical insight is not just identifying that a country has gone offline, but determining within the hour why: whether due to a storm, a severed cable, or a deliberate action. Each scenario leaves a distinct trace in the data, and rapid differentiation is the core purpose of our monitoring.

Why quiet is worth watching

It may seem that a monitoring map is only valuable during crises, but the opposite is true. The green state is the achievement. Three billion people connected, hour after hour, across 238 countries, represents an extraordinary, fragile, and continuously maintained system. The only way to ensure its stability is to measure it during periods of calm. A quiet map is a promise: the moment stability breaks anywhere on Earth, the pixel will change, and GeoCables will already be watching.
