About this network

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.
