It is seen behind 39 upstream networks, most often AS38880 (Micron21 Datacentre Pty Ltd) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 784 downstream networks. 64% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 95% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS4826 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
