Issue with Payment Initiation service

Introduction

On 25th of November between 9:07 and 9:35 (CET), Tink experienced intermittent technical issues that impacted our Payments products for selected Customers, for a total of 20 minutes, during which end-users were unable to initiate payments.

Root Cause Analysis

Payments were impacted due to one of the components within the Payments service experiencing an undesired behavior that led to a cascading effect on other dependent components and eventually preventing payments from initializing.

Remediation

The faulty component in question was disabled and payments traffic was switched to an alternative flow, which allowed payments to be initiated properly.

Follow-up actions

Tink is planning to implement the following remediation actions:

1. Optimization of the faulty service
2. Improved monitoring and alerting for the platform
3. More hardware resources configured for the faulting services
4. Implementation of automatic restarts when similar faults are detected
