Peers

AS8501 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

AS8501 connects to the global Internet via at least 5 upstream providers. In this setup, AS8501 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.

Downstreams

AS8501 serves as a transit provider the following ASes, delivering the BGP routes needed for global connectivity. This downstream relationship underscores AS8501's role in extending Internet access beyond its own infrastructure.
