Infrastructure Wars: Who Controls the Internet Backbone?
By Jordan Lee
The internet's backbone infrastructure is more contested and politically significant than most users realize. Understanding who controls these critical systems is essential to understanding global power dynamics in the digital age.
Under the surface of the consumer internet lies a complex infrastructure of submarine cables, data centers, and network interconnection points. These physical systems are owned and operated by a diverse set of actors: government agencies, multinational corporations, and consortiums of companies.
Submarine cables connect continents and carry the vast majority of international data traffic. Control over these cables gives enormous power. Several countries have attempted to restrict or control submarine cable infrastructure. Some companies have invested in private cable systems to avoid relying on others.
Data center locations are strategically important. Companies operating in different countries must navigate different regulatory requirements and political pressures. The move toward edge computing and distributed infrastructure is partly driven by the desire to reduce dependence on centralized control points.
Network interconnection points—where traffic between different networks exchanges hands—are critical choke points. Companies that control these points have significant leverage over network traffic and can potentially monitor or manipulate data.
The geopolitical implications are substantial. Countries are investing in building independent internet infrastructure to reduce dependence on other nations. Companies are investing in redundancy and diversity to avoid being locked into reliance on particular providers.
As the internet becomes more central to national economies and security, control of infrastructure becomes increasingly important.
