Summary

BSO (BSO IX Reach Ltd)

United Kingdom · AI-generated

transit legacy

BSO is BSO, a global network operator best known for low-latency connectivity for

financial markets. The registered entity is BSO IX Reach Ltd, reflecting BSO's

acquisition of the UK carrier IX Reach.

What it's used for

  • Wholesale connectivity: point-to-point circuits, cloud on-ramps, and remote peering into internet exchanges across Europe, North America, Asia, the Middle East, and Africa.
  • Low-latency routes between financial trading venues, the business BSO built itself on.

Notable

  • Carrier and transit address space rather than eyeball space: IPs here are network infrastructure and wholesale customers, not home broadband.
  • Remote peering is a large part of the IX Reach side of the business. It lets a network appear at an internet exchange where it has no physical presence, so traffic seen at an exchange via this ASN may well originate somewhere else entirely.

Interesting

  • BSO acquired IX Reach in 2019 and later folded its core network in, combining a financial-markets latency specialist with an exchange-connectivity and remote-peering provider.
