4. postmortem Jun 05, 2026, 05:10 PM UTC

   **Postmortem: INC222639 – Outgoing and Incoming Wire Transfers Delayed** On June 1, 2026, between 7:25 and 10:55 a.m. PT \(10:25 and 1:55 a.m. ET\), a Central 1 third-party tool used for wire reviews intermittently displayed an error to Central 1 users. Despite the error messages, wire transfers continued to process in the background. Some transactions had to be manually restarted, causing a brief delay. The issue was traced to a problem with our external vendor, Fiserv’s Enterprise Payments Platform \(EPP\), which supports wire processing. Service was fully restored after the vendor made the necessary fixes, and normal operations resumed. To resolve the issue, Fiserv completed a system configuration update at 9:24 a.m. PT \(12:34 p.m. ET\), addressing a compatibility problem that was causing the errors. **Point of Failure:** Fiserv has performed a preliminary root cause analysis and determined that this incident was caused by a Fiserv vendor-managed component \(Ingress Controllers\) that was upgraded across several environments. This triggered the outage due to incompatibility with a Fiserv monitoring component used within the affected configuration \(Ingress Controller setup\). **Corrective Actions:** Fiserv is working with Microsoft to reduce the likelihood of recurrence by enhancing validation and testing procedures for configuration changes and ensuring that all server dependencies are identified and addressed before deployment. Additional monitoring will also be implemented to detect and address EPP UI proxy errors in real time. At Central 1, we improved our monitoring to catch issues with third-party systems earlier. We are also reviewing vendor support and escalation processes to help resolve issues faster. In addition, we’ve evaluated our internal incident response procedures to improve coordination and response during vendor-related outages. * Central 1 has implemented an automated daily test at 4:00 a.m. PT \(7:00 a.m. ET\) to confirm outgoing wire transfers are working properly and to detect issues earlier. We sincerely apologize for the disruption and the impact this incident had on your operations, particularly for time-sensitive wire transactions. We appreciate your patience while services were restored. Liz Ackroyd, Manager of Client Support Services [[email protected]](mailto:[email protected]) | 905.301.1337
