AS6830 LIBERTYGLOBAL Liberty Global formerly UPC Broadband Holding, aka AORTA

Liberty Global's pan-European backbone (LIBERTYGLOBAL, historically AORTA /

UPC Broadband) — the core network behind its cable-broadband operators.

What it's used for

• Backbone and internet connectivity for Liberty Global's European cable brands (such as Telenet, Sunrise/UPC, and its joint ventures), plus wholesale.

Notable

• Largely an "eyeball"-serving backbone: it aggregates and carries traffic for millions of cable-broadband subscribers across several countries.
• Liberty Global's structure changes as it buys, sells, and forms JVs (e.g. Virgin Media O2 in the UK), so the operators behind it shift over time.

Interesting

• "AORTA" was the long-time name of the UPC/Liberty European backbone and still shows up in its network naming.
