⚠️ Supernode 2 has been removed ⚠️

Supernode 2 (node 570) was located at 1196 Metropolitan Avenue in Brooklyn New York. On October 7th, 2018 it was taken down due to a landlord dispute.

The information below is a point of reference for how supernode 2 was configured.

Backhaul

A pair of AirFiber 24s was donated to NYC Mesh and was deployed between 227 and 570 to provide Brooklyn with a near 1Gbps backhaul link to Supernode 1, the Manhattan area of the mesh and the internet.

Battery backup

Shortly after initial installation we noticed the node would go down on a somewhat regular basis. After some investigation and discussion with building residents, the culprit was revealed to be a circuit breaker being tripped by power hungry air conditioners. To insulate the node against short power outages like this we built a simple backup power system out of a 12 volt battery and integrated inverter / charger / automatic transfer switch.

Routing

570 currently uses BGP to exchange routes with its mesh peers. We hope to upgrade this node to support more dynamic routing protocols soon.
