As the Internet continues to grow, questions of accessibility and infrastructure equity persist. In the increasingly competitive telecommunications industry, profit-seeking firms continue to upgrade infrastructure in select market areas creating an uneven spatial distribution of access opportunities. This article utilizes a longitudinal database of Internet infrastructure development, highlighting fiber-optic backbone points of presence (POP) established by commercial Internet service providers to examine city accessibility to the commercial Internet. Results indicate that many larger metropolitan areas maintain dominant shares of telecom infrastructure, but several midsized metros are emerging as important centers for telecommunication interconnection.
