ISE Announces Colocation Service

The International Securities Exchange (NYSE: ISE) today announced the launch of a colocation service, providing ultra low-latency connectivity to ISE’s options and stock exchanges. With the colocation service, ISE member firms will be able to place their trading hardware in the same building as ISE’s data center, which will facilitate network transit times of less than 200 microseconds. "Through this colocation offering, there is now an ultra low-latency solution for market makers and high-frequency traders who conduct trading strategies where execution speeds are critical. This latest service underscores our ongoing commitment to ensure that our members have a range of customized alternatives to support their specific connectivity requirements,” said Daniel Friel, ISE’s Chief Information Officer. Quality Technology Services (QualityTech), the facilities management firm at ISE’s data center, is offering the colocation service in conjunction with ISE. QualityTech will connect members to the ISE servers located in the same building via a secure and certified cross-connect. They will also offer a range of related services including space, power, and a managed technology environment. To support its members in determining the appropriate connectivity solution for their particular trading needs, ISE offers a consultative service and referrals to the best and most flexible technology services and vendors.
