Peers
AS27138 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
AS27138 connects to the global Internet via at least 1 upstream provider. In this setup, AS27138 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.
Downstreams
AS27138 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
