Mario Santamaría's obsession (from Burgos, based in Barcelona) is the material infrastructure of capitalism, which inevitably runs through the internet: submarine cables, data centres, servers, antennas, routers and repeaters. Ten years ago he set out on a fifteen day physical journey from his home in Barcelona to the server hosting his website in Italy, tracing the cables, routers and antennas that separate the two locations. Since then, he has travelled half the world running internet tours: guided visits to the network infrastructures that surround us, as informative as they are surprisingly entertaining.

In this talk, Santamaría explores the internet as a tangible geography, where cables, data centres and protocols shape not only the network but also imaginaries and power relations. His practice proposes a journey through the physical layers that sustain and overflow the digital, revealing how different systems of circulation of data, energy and matter share logics and tensions that invite us to rethink our relationship with contemporary infrastructures.

We have invited him to Sónar+D because when the "cloud" becomes too comfortable, someone has to remind us that the digital is also geography. And that, if needed, you can walk to it.
