Transaction Monitoring, Payment Method Check Advanced issues
Resolved after 2 hours 44 minutes, on November 19, 2025.
Root Cause: The issue was caused by significantly increased response times from the external provider API The system continued waiting for risk-scoring responses until reaching the maximum timeout, which led to slow queue processing and delays for handling of part of transactions. Next Steps: We will enhance our queue-management logic to better handle scenarios where third-party providers are involved in the scoring process.
