The recent rapid growth of the Internet has avoided scrutiny from urban pla
nners as little information is available from which to assess its impacts o
n cities and regions. As a result, explanations of the relationship between
telecommunications and urban growth are overly simplistic, forecasting eit
her the centralization of decisionmaking in so-called 'global' cities or wh
olesale urban dissolution. Based on two measurements of Internet geography-
domain name registrations and backbone networks-this study finds that acces
s to advanced communications technologies have broadly diffused across a wi
de group of medium-sized and large-sized metropolitan areas. Finally, the i
mplications of these findings suggest a need to rethink global cities and a
practical need to address the growing divide between network cities and th
e rest of the urban world.
