Tubes: A Journey to the Center of the Internet
Source: https://www.harpercollins.com/products/tubes-andrew-blum ↗
Blum is a journalist who began investigating the physical internet after a squirrel chewed through his cable connection.
The book follows him from that hole in his garden to submarine cable landing stations in Portugal, internet exchange points in Frankfurt, and data centers in Oregon.
It is narrative journalism at its best — concrete, sensory, and stubbornly material about an infrastructure most people experience as pure abstraction.
Blum shows that the internet has a geography, and that geography reflects economics, history, and power in ways that matter for anyone building products on top of it.
The writing makes visible what engineers take for granted and what users never see.
For product people accustomed to thinking in APIs and dashboards, it is a necessary correction toward the physical substrate underneath.
Central argument
Blum argues that the internet is not a cloud or an abstraction but a physical infrastructure with a specific, mappable geography — cables, buildings, and exchange points whose locations were determined by historical accident, economic incentive, and geopolitical constraint rather than any rational design. By tracing actual fiber routes from a chewed cable in his garden to submarine landing stations and internet exchange points in Frankfurt and data centers in Oregon, he demonstrates that digital experience is downstream of physical decisions made decades ago. The central finding is that this material substrate concentrates power and vulnerability in ways that remain invisible to nearly everyone who depends on it.
Critique
The book's commitment to narrative journalism — sensory, character-driven, rooted in the moment of reporting — means it captures infrastructure as it existed circa 2012 and largely avoids the harder analytical question of what this physical concentration of ownership actually means at a systemic level. Blum describes the geography of the internet without fully interrogating the political economy that produced it: why certain companies and nation-states control critical nodes, and what mechanisms could contest that control. A reader wanting to think rigorously about infrastructure as a site of power rather than a destination for wonder will find the book stops just where the argument gets most difficult.
Why it matters for product
For a CPO, the book is a corrective to the abstraction bias that product thinking inherits from cloud-native development — the assumption that infrastructure is elastic, neutral, and invisible. Latency, data residency requirements, regulatory constraints on cross-border data flows, and the resilience risks embedded in vendor concentration all trace back to the physical geography Blum documents, and ignoring that geography produces product strategies that fail at the edges of the map. Understanding that the internet has choke points with specific owners and jurisdictions changes how you think about platform risk, localization decisions, and the credibility of any availability guarantee you make to users.
