Malfunction in payment confirmation triggers.

Date: January 11, 2026
Document Type: External Client Communication

Executive Summary

On January 11, 2026, our payment processing service experienced a partial degradation affecting some payment transactions. The incident lasted 3 hours and 45 minutes, during which 3,012 payment attempts were impacted.

We sincerely apologize for any inconvenience this may have caused to your business operations.

Incident Overview

What Happened

During a period of increased transaction volume, our payment processing queue experienced elevated load. This resulted in:

• Delayed processing of some payment requests
• A portion of payment attempts failing due to processing timeouts

Timeline (UTC)

Root Cause

A gradual degradation in processing performance escalated into delayed payment execution, caused by:

Payment processing was impacted as a downstream effect of reduced throughput in a supporting internal service.

1. An increase in transaction volumes surpassed the initially provisioned processing capacity
2. Internal system dependency experienced performance degradation under load
3. Processing queue depth grew faster than the system could recover

Resolution

To restore service, our engineering team:

• Increased payment processing capacity by 50%
• Scaled up worker processes to handle higher throughput
• Increased payment processing capacity to deal with the load, as well as increasing overall excess thresholds
• Performed maintenance on internal system dependencies
• Monitored queue recovery until processing returned to normal

Resolution required a phased mitigation approach: first stabilizing the supporting internal service, then increasing processing concurrency, and finally allowing the backlog to drain. Because the incident manifested as gradual degradation with queue build-up, recovery time included both mitigation and queue catch-up.

Preventive Measures

We are implementing the following improvements to prevent similar incidents:

• ✅ Completed: Increased processing across all services, including internal dependencies.
• 🔄 In Progress: Implementing proactive queue monitoring and alerting
• 🔄 In Progress: Optimizing internal systems to improve performance under high load
• 📋 Planned: Establishing traffic notification process with partners for capacity planning
