          Abstract

          Este artigo visa reafirmar o papel do espaço no estudo das Novas Tecnologias de Informação e Comunicação (NTICs). Examinamos a topologia dos backbones de internet no Brasil usando as ferramentas matemáticas da teoria dos grafos. Através do cálculo de índices de centralidade (proximidade e intermediação), bem como de outras técnicas quantitativas, as redes físicas que compõem a internet são relacionadas à rede urbana preexistente, mostrando que em suas características gerais o funcionamento da internet não subverte a geografia econômica do país, a despeito do ideário antigeográfico suscitado por parte da literatura sobre os impactos da tecnologia.

          Translated abstract

          This paper aims to reassert the role of space in the study of the New Information and Communication Technologies (NICTs). We examine the internet backbone topology in Brazil using mathematical tools from graph theory. By calculating centrality indexes (closeness and betweeness) and other quantitative techniques as well, the physical networks that comprise the internet are compared to the existing urban network. We show that, in its general features, the spatial dimension of the internet does not subvert the previous economic geography, despite the anti-geographic bias raised by part of the literature on technology impacts.
