Summary
Lumen (Global Crossing / Level 3 legacy)
transit backbone legacy
A major global backbone (LVLT-3549) now operated by Lumen — the former
Global Crossing network, which Level 3 acquired before merging into Lumen.
What it's used for
- Global IP transit and wholesale backbone connectivity, especially on long-haul and submarine routes Global Crossing originally built.
Notable
- Sits alongside AS3356 (the Level 3 core) inside Lumen; 3549 is the absorbed Global Crossing footprint, still announced under its own ASN.
- A Tier 1-class backbone reaching the whole internet via peering.
Interesting
- Global Crossing famously laid a global submarine-cable network in the late 1990s; that fibre lives on inside Lumen today.
