Peers

AS73 does not have any direct peering agreements. Instead, its global connectivity is achieved through transit providers. While this setup ensures comprehensive reach, future peering could reduce latency and optimize route efficiency.

Upstreams

AS73 connects to the global Internet via at least 1 upstream provider. In this setup, AS73 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.

Downstreams

AS73 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
