Standing Maintenance Window

Cboe performs scheduled maintenance to CFE and Indices connectivity infrastructure during a standing maintenance window every Friday from 8:00 p.m. - 10:00 p.m. ET. Customers should expect potential disruption to their connectivity during this window.

Cboe will not provide advance notification for maintenance activities performed within this standing window. Customers will be notified separately for any maintenance scheduled outside of this window in accordance with standard change notification procedures.

To minimize service disruption, Cboe will perform maintenance to the primary and secondary paths at separate times during the window, ensuring that not all access to CFE and Indices is simultaneously affected. Customers with connectivity to both the primary (Secaucus, NJ) and secondary (Chicago, IL and Elk Grove Village, IL) data centers are encouraged to ensure their systems are configured to utilize redundant paths during this window.
