Eurex Exchange’s T7 Disaster Recovery Test on 17 June 2023

Eurex Circular 028/23 Eurex Exchange’s T7 Disaster Recovery Test on 17 June 2023

1.  Introduction

On Saturday, 17 June 2023, Eurex Exchange will offer a test scenario according to its T7 disaster recovery concept. This particular DR scenario renders the T7 back-end of the Equinix data centre (FR2) inaccessible. The co-location facility will still be accessible so that co-location customers can also access the disaster recovery infrastructure.

The DR test window will be provided on Saturday afternoon (Central European Summer Time) according to the following schedule:

Start of DR scenario test

13:00 CEST

End of DR scenario test

16:00 CEST

Start of production environment re-connect test

17:00 CEST

End of production environment re-connect test and shutdown of T7 production

18:00 CEST

The T7 production environment will be re-started for the business day 19 June 2023 on Sunday evening, 18 June 2023, at the usual time.

Learn more about our T7 Disaster Recovery test concept on our dedicated initiative page under the following link: Support > Initiatives & Releases > Project Readiness > T7 Disaster Recovery Test. System documentation, circulars, timeline and more information is available there for you.

2.  Required action

Participation in the T7 Disaster Recovery Test is not only strongly recommended by Eurex but it is also seen as an essential part of the industry’s disaster recovery readiness. Please make sure that your Chief Operations Officer as well as your Chief Compliance Officer are made aware of the test and that it is treated with the required priority. 

Eurex kindly requests all Eurex Trading Participants to regularly take part in the T7 disaster recovery test. 

Participation will serve to ensure that all requirements and demands for the transition to the disaster recovery environment are met and that the necessary emergency procedures are in place and have been successfully executed on a regular basis. 

The validation of these emergency procedures is crucial for Eurex and its Trading Members not only to be compliant with the respective Business Continuity Processes but also to ensure continued market integrity.

All Trading Participants are kindly requested to provide Eurex with the respective feedback regarding their T7 Disaster Recovery Test planning by Friday, 19 May 2023 at the latest. 

Feedback can be provided using the T7 Disaster Recovery Test Feedback Form. For your convenience an online submission process has been set up:

Please enter your dedicated Eurex PIN in the online questionnaire. The PIN for your company has been sent to the Central Coordinator.

3.  Details of the initiative

This particular DR scenario will simulate a partial outage of the Equinix data centre (FR2) facility. In such a disaster recovery scenario, the infrastructure regularly used for the T7 simulation environment will be re-used to serve as disaster recovery production infrastructure. However, the co-location facility will remain up and running and affected Members which have access to that disaster recovery infrastructure will be able to participate in the test.

During the DR test exercise, production reference data will be used, including User IDs, T7 GUI SSH keys and ETI/FIX LF sessions. Changes which have been made to this reference data will NOT be copied back to the production environment after the test. It is not advisable to perform any changes to this data during the test exercise.

While order entry, modification and deletion will be possible during the DR test exercise, any order book or trading information created during the DR test exercise will NOT be transferred back to the production environment. 

The following Eurex T7 interfaces will be available during the DR test exercise:

  • Eurex T7 Trader- and Admin-GUI
  • Enhanced Transaction Interface (ETI)
  • FIX LF interface 
  • Eurex Market Data Interface (MDI)
  • Eurex Enhanced Market Data Interface (EMDI)
  • Enhanced Order Book Interface (EOBI)
  • Reference Data Interface (RDI)
  • Reference Data File (RDF)
  • Common Report Engine (CRE)

Trading Participants taking part in the DR test exercise can expect to receive market data via MDI, EMDI and EOBI and read reference data via RDI or RDF. Order entry will be possible via ETI, FIX LF and the Trader GUI. 

The disaster recovery test exercise can be regarded as successful when at least one of the three following conditions have been met:

  • EITHER a message “Connection Test Eurex <hh:mm:ss>” appears with an increasing sequence number in the market news view (news board) of the T7 Trader GUI or the T7 Admin GUI 
  • OR a successful session or trader login via ETI has been performed and EMDI/EOBI/RDI heartbeats have been received.
  • OR a successful session or trader login via FIX LF has been performed and EMDI/EOBI/RDI heartbeats have been received.

The following Eurex T7 interface will NOT be available during the DR test exercise:

  • Extended Market Data Service

Deutsche Börse AG will also be offering a disaster recovery test opportunity for the trading venues Xetra and Börse Frankfurt on the same day, allowing both Eurex and Cash Markets Trading Participants to test DR scenarios simultaneously.

Please refer to the document “T7 Disaster Recovery Concept - Interface Configuration Details” for further details on the test scenario and all required network changes.

The updated document will be available on the Eurex website under the link:

Support > Initiatives & Releases > T7 Release 11.1 > Network Access

After the DR test has been completed, the regular production environment will be made available for a certain time period for a re-connect test in order to allow Trading Participants to adapt their configurations and test connectivity to the production environment if required.
