Peers

AS8508 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

AS8508 connects to the global Internet via at least 2 upstream providers. In this setup, AS8508 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.

Downstreams

AS8508 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
