Affected system: WIPay host (ECR protocol)
Impact: Recurring interruptions of Callback service. Still partly persisting. Transactions are still possible, but feedback with transaction result may be correctly received, delayed, or not received at all. This differs per terminal. When the system is 100% up, the not received transaction results can be requested via a status request (accompanied by a SSAI, reference or transaction ID).
Extra information: The rollback last night was successful. Apparently, this action failed to provide the expected solution, despite positive initial indicators. Analyses are ongoing to identify a structural fix.
