Dark Fibre Network Drift was a collective walk, organised by John Wild, following the route of underground fibre-optic cables linking the core data centres that form the London Internet Exchange. The walk included spoken word by Robin Bale and experiments using software defined radio to hack the sonic world of machine to machine communications. Around 30 walkers met at 14:00 on Sunday 27 October 2019, Chrisp Street Market, Poplar, East London.
When telecommunications companies lay fibre-optic cable, they lay extra to mitigate the future cost of having to lay it again. Dark fibre refers to the unused fibre-optic cables. The walk used a map of London’s underground dark fibre network to chart a route through East London that focused on the central nodes in the UK’s internet. Our first destination was Coriander Avenue, a 15-minute walk from Chrisp Street Market, on the south side of East India Dock Road. Coriander Avenue is a nexus point in the London Internet Exchange (LINX) and, by definition, within the UK's internet infrastructure.
Coriander Avenue and its surrounding streets, Saffron Avenue, Nutmeg Lane, Rosemary Drive and Oregano Drive, house four of the core LINX data centres: Telehouse North, Telehouse North 2, Telehouse East and Telehouse West. Alongside the four Telehouse data centres is the Global Switch Campus, comprising two data centres, Global Switch London East and London North. Global Switch London East hosts financial services customers and enterprises including Google, Fujitsu, Claranet and Datapipe. Global Switch North is the termination point of Atlantic Crossing 1 (AC1), the main subsea optical submarine telecommunications cable system, linking the UK directly to the United States.
From Coriander Avenue, the walk followed an arm of the dark fibre network south past Sovereign House and Meridian Gate data centres, to Equinix LD8 which houses Amazon’s UK servers. The experience of walking these sites was powerful. The buildings are imposing, anonymous and secretive and induce a self-consciousness in those who enter their terrain. The physicality of the data centres exposed their integration into wider networks of infrastructure, in particular their use of electricity.
Telehouse North Two, for example, contains its own on-campus 132 kV grid substation that is directly connected to the National Grid. Such heavy demands for electricity raise important questions about both the environmental impact of cloud computing and why so much data is being stored. The confrontation with the sheer scale and physicality of cloud computing is one of the fundamental strengths of investigating the digital city through walking.
We are sold a belief in cloud computing as light, impermanent and invisible. The reality is imposing, industrial and infused with a paranoia-inducing hostile ambience. The walk enabled a collective confrontation with the materiality of the UK’s internet infrastructure that challenged the ephemeral image of cloud computing and created an event where new spatial imaginaries could emerge through the practice of walking and talking together.
