Upstreams
AS6855 connects to the global Internet via at least 3 upstream providers. In this setup, AS6855 acts as a customer, subscribing to these transit services to obtain full BGP routing information and ensure reliable, redundant access to external networks.
Downstreams
AS6855 serves as a transit provider the following ASes, delivering the BGP routes needed for global connectivity. This downstream relationship underscores AS6855's role in extending Internet access beyond its own infrastructure.
