Peers
AS29990 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
AS29990 connects to the global Internet via at least 6 upstream providers. In this setup, AS29990 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.
Downstreams
AS29990 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
