Amazon's New Cable Highlights Both the Ambitions and Vulnerabilities of Ireland's AI Infrastructure

Amazon's new transatlantic fiber-optic cable has become a symbol of Ireland's tech ambitions. It has also exposed the risks of the country's chronically low defense spending, Bloomberg reports.

Почему Ирландия важна для ИИ-инфраструктуры

For decades, Ireland has drawn data centers from the biggest tech companies, including Amazon, Google, Meta, and Microsoft, thanks to its low corporate tax rate, EU membership, and English-speaking workforce. The AI boom has sharply increased demand for compute in the country. By various estimates, data centers already consume about a fifth of Ireland's electricity, and EirGrid, the national grid operator, has repeatedly warned of limits on connecting new facilities in the Dublin area.

• Amazon has laid the new cable across the Atlantic
• Ireland is one of Europe's key data center hubs for Big Tech
• Data centers already consume a significant share of the country's electricity, estimated at about a fifth
• Ireland's defense spending is chronically lower than that of its EU neighbors

В чём риск для безопасности

Subsea cables carry the overwhelming majority of the world's internet and cloud traffic, including data used to train and run AI systems, and they are physically highly vulnerable. In recent years, incidents of subsea cable damage in the Baltic Sea have become more frequent, and investigators have linked them to vessels from the so-called shadow fleet. Ireland, meanwhile, has no full-fledged navy or air force capable of protecting its own waters and airspace. The country has historically maintained neutrality and spends one of the lowest shares of GDP on defense in Western Europe. For years, neighboring states have effectively patrolled part of its airspace.

Как это связано с ИИ, а не только с интернетом

Transatlantic cables like Amazon's new route aren't just a "pipe" for web traffic. They carry data synchronization between data centers, model training and serving for customers on both sides of the Atlantic, and traffic for cloud AI services that depend heavily on low latency. The more AI compute concentrates in Ireland, the more costly any connectivity outage becomes, and the wider the gap grows between the country's digital ambitions and its ability to physically defend them.

При чём здесь Amazon

Amazon is no outside observer here. It is one of the main builders of Ireland's digital infrastructure: for many years, its cloud division AWS has run one of Europe's largest data center clusters in its Dublin region, which serves customers that include those running AI workloads. The new cable directly increases bandwidth for traffic between these facilities and the US. In other words, it deepens Ireland's dependence on the company as an anchor tech investor.

Что это значит

The more global AI infrastructure depends on a handful of key hubs like Ireland, the more pressing the question of physically protecting the cables and data centers that keep it running.
