Peers

AS1239 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.

AS174 AS209 AS286 AS701 AS1299 AS2828 AS2914 AS3257 AS3320 AS3356 AS3491 AS5511 AS6453 AS6461 AS6762 AS6830 AS7018 AS7713 AS12956 AS16509 AS199524

Upstreams

There are currently no upstream providers for AS1239. 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

AS1239 serves as a transit provider the following ASes, delivering the BGP routes needed for global connectivity. This downstream relationship underscores AS1239's role in extending Internet access beyond its own infrastructure.
