CME STP FIX - Update to New Release Host Connectivity - Now Available

CME STP FIX service will now incorporate the following managed and regional connectivity options in the New Release environment to better align functionality with Production.

CME STP FIX - Update to New Release Host Connectivity
Connectivity Option	Hostname	IP Addresses	Port	Asset Class	Usage
Managed	stpfix.api.uat.cmegroup.com		443	All	Client systems connect to one Host for all entitled STP trade data. CME Group manages regional connectivity. Customers should account for DNS update time during regional IP switch. Client systems must reestablish connections and resubscribe after weekly regional switch (Weekly on Wednesday) disconnections to resume receiving post-trade messages.
Regional	stpfix-a.api. uat.cmegroup.com	208.112.193.131	443	All	Clients can connect to both regions in parallel providing flexibility and redundancy. Clients can subscribe to the same or different STP trade data across regions based on their entitlements. Sequences of messages are not guaranteed to be the same across regions.
	stpfix-b.api. uat.cmegroup.com	208.112.193.10

Client systems are required to target the hostname(s). IPs are provided for convenience of local client side whitelisting purposes only. Clients can continue to use their existing entitled API IDs with this Host change.

This change does not affect Production connectivity.
