Form3 were alerted to ongoing latency in successful test payment submissions being updated to a final state on the FPS simulator for Form3 API Gateway customers.
Investigations identified a network configuration issue impacting the status update logic after the payment had been processed.
Form3 engineers identified a fix which was then tested and released, a period of monitoring confirmed no ongoing impact from 21:00 BST on the 27/09/21. We have also confirmed all impacted payments have reached the correct final state.
Form3 continue to proactively monitor the Staging environment to identify service enhancement and prevent impact to payment processing.
