Upgrade to SSL certificates services.cmegroup.com PRODUCTION

Effective Sunday, January 19, 2014 (trade date Monday, January 20, 2014), the SSL certificates found on our servers that service: services.cmegroup.com applications will be changed with new certificates with new expirations.

While we are confident the upgrade will be seamless to most if not all users, some API users in the past, had connectivity issues with SSL upgrades and or changes. These issues, which were rare, were based in either keystore problems that are encountered within the user's application, or clients failing to find the correct CERTIFICATE CHAIN

The certificates will be available in PRODUCTION Sunday Afternoon approximately 1 PM EST. We urge users to test connectivity as soon as possible, so if any issues are encountered, they can be worked through so users will avoid any interruption in service.
