      Removal of RC4 Cipher Suites

      CME Group is committed to information security. To deliver the best security and customer experience, we are eliminating support of the RC4-based cipher suites for CME Group web-based applications, APIs, and service in Certification, New Release, and Production environments.

      As of this change, customers relying on RC4 cipher suites will no longer have access to these web-based applications, APIs, and services.

      Please note: CME Group strongly encourages customers to verify connections so those environments continue to function properly.

      RC4 cipher suites support will be removed as follows:

      Customers following CME Group Web Browser Standards should not be impacted by this change. However, if customers connect through a proxy, they should ensure their proxy utilizes one or more of these CME Group supported ciphers:

      • TLS_RSA_WITH_AES_256_CBC_SHA256
      • TLS_RSA_WITH_AES_128_CBC_SHA256

      The change in Certification and New Release environments is complete.

      Leap Second Impact

      CME Clearing House processing will be paused from 18:55 - 19:05 Central time (CT) on Tuesday, June 30, for the leap second, including CME ClearPort. CME Group strongly recommends customers finish their processing prior to 18:55 CT and do not access any CME Clearing House systems during this window.

      CME Group uses Network Time Protocol (NTP) to synchronize time and maintain time accuracy. On Tuesday, June 30 (trade date Wednesday, July 1), a positive leap second will be added after 18:59:59 CT. A leap second is a one-second adjustment that is added to Coordinated Universal Time (UTC) to account for variability of the earth’s rotation.

      Trades submitted via CME ClearPort during the Leap Second window will be queued. Once the window is complete, all trades will be processed in the order received. Customers will not receive acknowledgements or trade reports until after the window.
