In 2023, CME Group is upgrading its GLink network infrastructure at the CME Co-Location Facility in Aurora, IL.

This network upgrade consists of:

• Replacement of the existing end of life (EOL) Juniper switches with new Arista switches which will utilize new customer ports and new CME IPs;
• Introduction of a new GLink Demarc Cable providing customers with equidistant connectivity to any rack unit (RU) in their cabinet.

The new GLink switches will also expand capacity to support future growth while the new GLink Demarc Cable will allow customers to optimize their CME Co-location Licensed Space. The new GLink infrastructure is anticipated to be ready in Q3 2023 with customer testing and cutover to the new network taking place during Q3/Q4 2023.
