Peers
AS2923 actively fosters the following peering relationships that enhance network performance through direct, settlement-free traffic exchange. Even with a modest number of peers, each connection serves as a strategic asset—optimizing routing, reducing latency, and minimizing transit costs.
Upstreams

Downstreams
AS2923 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
