As of 22nd October 2026, AS26827 (EPB Fiber Optics), an access network registered in the United States with ARIN, originates 21 IPv4 prefixes covering 115k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,189th-largest of the 79,655 networks we see originating IPv4, and the 699th-largest of 18,475 in the United States. It is seen behind 10 upstream networks, most often AS2914 (NTT America, Inc.) and AS3257 (GTT Communications Inc.), and in front of 24 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS26827 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.
