Peers
AS5728 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

Downstreams
AS5728 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
