Peers
AS21628 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
There are currently no upstream providers for AS21628. This means the network doesn’t subscribe to traditional upstream services for global connectivity. Instead, it likely relies on direct peering or its own infrastructure to reach external networks. While this can reduce transit costs, it requires a robust peering strategy to maintain broad reachability and ensure redundancy.
Downstreams
AS21628 currently has no downstream networks, meaning it does not serve as a transit provider to customer networks.
