Description
This notice announces a proposed rule change filed by Nasdaq MRX, LLC, which has been made effective immediately by the Securities and Exchange Commission (SEC). The rule change involves amendments to Rule General 8 to expressly list non-contiguous intrafirm cabinet connectivity as a subset of Fiber connectivity and to amend the fees applicable to that service. The proposal requires all data center customers seeking non-contiguous intrafirm cabinet connectivity to obtain that connectivity directly from the Exchange, prohibiting third-party providers within the Exchange's data center halls. The changes aim to enhance operational integrity, auditability, and oversight of the connectivity infrastructure within the Exchange's data center environment.
