NYC Mesh: Community Internet Infrastructure
NYC Mesh is a community-owned, volunteer-run wireless internet service provider (WISP) that provides internet access to New York City residents using a mesh network of rooftop-mounted WiFi equipment. It is not primarily an emergency communication network, but its architecture and operational model provide important lessons for resilient community infrastructure.
Architecture
- Supernodes: High-capacity on tall buildings with fiber internet connections and long-range sector antennas covering large areas
- Hubs: Mid-tier nodes on rooftops, connected to supernodes and serving nearby buildings
- Standard nodes: Individual building connections, typically Ubiquiti NanoStation or LiteBeam equipment
Routing: NYC Mesh uses OSPF (Open Shortest Path First) for routing across the network, with BGP for internet uplinks. The network has multiple internet uplinks through different providers, providing redundancy at the connection level. See mesh networking technology →
Performance During the 2019 Con Edison Outage
During a major power outage in Manhattan in July 2019, NYC Mesh nodes in the affected area continued operating on battery backup while commercial ISPs failed. Residents with NYC Mesh connections maintained internet access while neighbors with commercial service lost connectivity.
- Distributed network architecture with multiple uplinks provides resilience that single-provider commercial service cannot
- Community-maintained networks can respond faster to local needs than commercial providers
- Physical infrastructure owned by the community doesn't disappear when a provider decides to cut costs
Governance and Sustainability
NYC Mesh operates as a volunteer-run nonprofit with key governance principles: open membership (anyone can join by installing a node), shared infrastructure (members contribute nodes and bandwidth), transparent operations (network status, documentation, and finances are public), and no commercial relationships with equipment vendors.
The network has grown continuously since 2014, demonstrating that volunteer-maintained infrastructure can scale sustainably when the governance model is sound. See the Neighborhood Network playbook → for how to apply these principles at a smaller scale.
Lessons
Community-owned infrastructure is more responsive to local needs.
NYC Mesh has repeatedly deployed nodes in neighborhoods underserved by commercial ISPs — particularly low-income areas where commercial providers don't see enough profit to invest.
Mesh architecture provides redundancy that commercial service cannot.
Multiple uplinks through different providers, combined with mesh routing that finds alternative paths around failures, creates resilience that even expensive commercial service doesn't match.
Open documentation compounds value over time.
NYC Mesh's detailed public documentation (docs.nycmesh.net) has enabled volunteers to join the project, contributed to similar networks in other cities, and created a shared knowledge base that has outlasted individual contributors.
Everyday use is the best test of emergency capability.
A network that serves thousands of users daily is far more battle-tested than one that sits unused waiting for an emergency. The reliability of NYC Mesh's everyday service is what makes it valuable in emergencies.
