Summary

Arelion (formerly Telia Carrier)

Global · AI-generated

tier-1 transit backbone

Arelion — formerly Telia Carrier — operates one of the world's top-ranked

Tier 1 backbones (TWELVE99, a nod to the AS number).

What it's used for

  • Global IP transit and wavelength/backbone services sold to ISPs, content networks, and enterprises worldwide.
  • Consistently ranked at or near the top of global IP-transit reachability rankings by connected networks.

Notable

  • A Tier 1: it reaches the entire internet through settlement-free peering and buys transit from no one.
  • Low announced IPv4 count is normal for a pure transit carrier — it moves other networks' traffic rather than hosting end users.

Interesting

  • Divested by Telia (sold to the Swedish investor Polhem Infra) in 2021 and rebranded from Telia Carrier to Arelion in January 2022. It's often used as a reference backbone in latency and routing studies.
