Once the issue caused by the faulty configuration change was identified, the engineering team quickly deployed a fix and unblocked SCA-enabled online card payments. To minimize the time it takes to detect issues, we have added additional detectors to promptly notify the engineering team of similar incidents. We are also proactively revising the sensitivity of our detectors and are continuously adding detectors to cover a wider range of scenarios and to ensure payments are continually processed.
