New DCV Operational Resilience Test Disaster Recovery Site (SRAD) Activation

Dear Participants,

As previously informed, DCV has been developing an initiative aimed at enhancing the resilience of its services platform and that of the securities market. The initiative’s purpose is to activate services from the disaster recovery site in a productive manner. During August and September, we informed the market of the activities required for all participants to log into the Disaster Recovery Site and achieve the previously mentioned objectives.

Considering the above, internal validations and a test with clients were conducted on August 23. Although participation levels were high, not all those involved attended, even when the outlined objectives were met. The results of the test, as well as the technical configurations for connectivity, were provided. After intense work with our participants, 94% met this objective.

Given the importance of this project to the entire market and to ensure the proper operation of the SRAD, we have decided to conduct a new validation test to access production services, particularly for DCV Evolution (DCVe), where we require the participation of the entire market on Saturday, October 11, 2025.

Once we ensure correct access to the SRAD and the DCV Evolution services platform, we can proceed with the final activation of the SRAD.

We would like to thank all the individuals who have participated in this process, and we invite you to look out for the details of this new activity.

The Commercial Department and Customer Service teams will continue to be available to support you and ensure proper preparation before the final activation.
