Scheduled
As part of our ongoing Centinel Data Center Migration, and as previously communicated, we are preparing to complete the Production DNS cutover that will transition remaining traffic to the Visa Data Center endpoints. To support a smooth transition and minimize disruption, we will continue to conduct controlled Production DNS “shock treatments" in April, followed by the final Production DNS cutover in early May. Please be advised that the dates referenced herein are subject to change and should any adjustments be required, we will provide timely notice.
Below is an overview of what to expect, key dates, and any actions required on your side.
What Will Occur and When:
April - May 2026 – Production DNS Shock Treatments These short duration activities are designed to validate client readiness and identify any remaining configuration issues prior to final cutover.
Date: April 8, 2026 Activity: Production DNS Shock Treatment #1 at 14:00 UTC Expected Duration ~30 minutes
Date: April 22, 2026 Activity: Production DNS Shock Treatment #2 at 14:00 UTC Expected Duration ~60 minutes
During these windows, traffic will temporarily be redirected to the new Visa endpoints (IP addresses). Clients who have not yet updated their integrations may experience brief processing interruptions during the shock treatment windows.
FINAL Date: May 6, 2026 - Full Production DNS cutover
Potential Client Actions Post Cutover (if not already completed): 1. Update all backend endpoints to use the Visa proxy domain (.cardinaltrusted.com). 2. Update IP allowlists / firewall rules to trust the new Production IP ranges. 3. Confirm your integration properly consumes response URLs returned dynamically (for DDC, Lookup, and Authenticate flows), rather than hardcoding legacy URLs. 4. Merchant Reporting Migration: Set up your Enterprise Business Center (EBC) access.
