The third chapter, “Gateway: From Cable Colony to Network Operations Center,” details the history of the cable station as a gateway to the network: it is a site of interconnection between national and international systems, a place where connections are made to local publics, and a zone where the border between system and environment is contested. The chapter moves through each of the three periods of cable development, documenting the shifting boundary between stations and their surrounding ecologies. In the colonial cable station, the cable worker’s body was the crux of network operations and the zone to be protected and regulated. As stations were remade during the Cold War, the border between the network and environment shifted from the body to the station’s built architecture. In the fiber-optic era, strategies of insulation now regulate the circulation of information. In each period, I highlight the investments in insulating the station and demarcating the inside and outside of the network, alongside the strategies of interconnection that ground the system in local micro-circulations. Looking at the network’s shifting interface with local publics, the chapter also illustrates how labor and a cable community remain key support systems for information networks.
