[Tokyo Stock Exchange, Inc.]
Until previously, Co-Location and Proximity Service users were limited to trading participants, information vendors, and independent software vendors (ISV). However, in October 2011, non-trading participant users were defined as "CSP" (Co-Location Service Supporting Providers). In addition to information vendors and ISVs, Co-Location and Proximity Services have also become available for hosting and network service providers.
