About this network

Virgin Media (NTL) — the UK's largest cable-broadband operator, now part of Virgin Media O2.

What it's used for

• Cable (and increasingly fibre) home broadband across the UK, plus business services.

Notable

• An "eyeball" network of UK residential subscribers. The NTL handle reflects its origin as the cable operator NTL, later rebranded Virgin Media.
• Runs its own cable access plant rather than reselling BT Openreach lines.

Interesting

• Virgin Media's cable network long offered some of the fastest widely available UK home broadband because it didn't depend on legacy phone-line DSL.
