The JSE’s Colocation facility provides the lowest-latency connection to JSE markets, allowing clients to host their infrastructure in the same vicinity as the infrastructure that drives the markets at the JSE. This enables low latency trading strategies through high speed trading and market data access.

The Colocation facility is a data centre facility housed at the JSE where clients can lease a rack for their server and other computing hardware in a secure environment right next to the JSE’s trading engine. The JSE’s enhanced facility provides the structure, cooling, power, bandwidth and physical security, while clients provide servers and storage within the facility.

The centre alleviates the administration burden of managing an on-site data centre, whilst allowing clients full access over their own server in the JSE data centre.
