Zai Outage History

Overnight, we experienced a temporary issue with card tokenisation services of an upstream provider. This caused some card payments and card storage attempts to fail between 10:42pm Sunday 3 May and approximately 12:15am Monday 4 May. The issue has now been resolved and services are operating normally. • You can safely retry any card card storage requests that were affected. • Our technical teams are currently verifying the status of payments processed during this incident and we’ll provide further guidance on next steps regarding payment retries as soon as possible. We’re sorry for this disruption and appreciate your understanding.

The issue has been resolved and service has been restored. Our teams are continuing to monitor closely to ensure ongoing stability. During the incident, American Express payment authorizations were impacted. Customers attempting to process payments with American Express cards may have experienced failed payment attempts. We recommend retrying any failed transactions. Our team is reviewing the status of affected payments, and if we identify cases requiring further action, we will contact the relevant customers directly. We apologize for the inconvenience and appreciate your patience while we worked to restore service.

We have resolved the issue and are continuing to monitor the system to ensure stability. During the incident, some “Create PayTo Agreement” and “Initiate PayTo Payment” requests may have failed. Our team is currently reviewing the status of any affected transactions. If we identify impacts requiring action, we will contact the relevant customers directly with further information.

Our investigation with our provider has confirmed this issue only affects payments using cards that were added to Zai’s system during the previous upstream outage on Friday 29 August. Cards added before or after the outage are unaffected and can be used to transact successfully. * As a workaround, if possible, impacted payers may re-add their card and retry their payment. * If re-adding the card is not possible, we are continuing to work with our provider to restore functionality for the affected cards. Given this workaround, we will close this incident, but a further update will be posted here once the permanent fix has been installed by our provider. If you're not already subscribed to receive updates, you may follow this incident for alerts. We apologise for this trailing impact from Friday's upstream incident.
