Facebook announces new terrestrial connectivity systems, Terragraph and Project ARIES, to bring Internet to underserved urban and rural areas, respectively

Context & Ripple Effects
This announcement is the hardware layer of a push Facebook had been assembling all year: two months earlier it confirmed work on millimeter-wave networks for Internet.org, and the year before that it had gone to orbit with the Eutelsat partnership beaming internet to Africa. Terragraph and Project ARIES split that terrestrial ambition by geography — dense cities served by rooftop-mounted millimeter-wave gear, sparse rural areas by long-range wireless.
First-order effects
- Terragraph gives urban carriers a fiber-substitute backhaul option in markets where trenching is the bottleneck, while Project ARIES targets operators serving low-density areas where fixed-line economics never worked.
- Both systems move Facebook deeper into network equipment territory, putting it alongside telecom vendors rather than just app-layer platforms.
Second-order effects
- The terrestrial systems give Facebook's parallel space bets — the Eutelsat link and later the Athena satellite constellation — a layered portfolio to sell to regulators and partners, with each technology covering where the others are weakest.
- Carriers gain negotiating leverage against traditional infrastructure vendors if Facebook's designs prove deployable at scale.
Third-order effects
- The sprawl of individual projects eventually forced consolidation: by 2018 Facebook folded everything under the Facebook Connectivity umbrella organization, and by early 2019 was deploying Terragraph and Express Wi-Fi across Peru, Nigeria, South Africa and California (the multi-country expansion).
- If the pattern holds, consumer internet companies become permanent owners of physical access infrastructure, blurring the line between platform and carrier.
The trend: Connectivity initiatives that began as scattered experiments — drones, satellites, millimeter-wave radios — are consolidating into a single infrastructure organization spanning terrestrial and orbital delivery.
