Is Clearhaus down?

Since 2026-10-14 07:15 CEST, we have seen an increased rate of rejections on Visa credit and debit transactions (Visa Direct OCT and AFT, sent via the /credits and /debits endpoints), including refunds of debits. This concerns these transaction types only, not Visa credit cards or Visa debit cards. Unfortunately, we see the same underlying issue as we did yesterday, and we are in constant communication with Visa trying to resolve the issue fully. Regular Visa authorizations, captures, refunds, and voids are unaffected, as are all Mastercard transactions. We are working with our upstream provider to investigate and will post an update when we know more.

A hotfix was deployed at 12:03 CEST, and the affected service is performing normally again. We are monitoring the situation and will post an update once we have confirmed the issue is resolved.

We deployed a stable fix at 2026-10-14 14:09 CEST which we have been monitoring and confirmed to be successful. We are still in communication with Visa to understand the root cause on the Visa side, but as there is no more impact of this incident, it will hereby be considered resolved. During the incident period 07:15–12:03 CEST, 86 % of Visa credits or debits received status code 50000. Impacted merchants will receive direct communication from us to clarify the actual state of the impacted transactions that received status code 50000 and a status message indicating “status unknown”.

Between 18:18 and 18:53 UTC, settlement data was unavailable in the Merchant API due to a database outage. Gateway transaction processing was not affected at any point. We apologise for any inconvenience.

Since 2026-10-13 08:16 CEST, we have seen an increased rate of rejections on Visa credit and debit transactions (Visa Direct OCT and AFT, sent via the /credits and /debits endpoints), including refunds of debits. This concerns these transaction types only, not Visa credit cards or Visa debit cards. Regular Visa authorizations, captures, refunds and voids are unaffected, as are all Mastercard transactions. We are working with our upstream provider to investigate and will post an update when we know more.

Since 2026-10-13 12:30 CEST, Visa Direct OCT and AFT, sent via the /credits and /debits endpoints), including refunds of debits, has been working as normal. We are monitoring the situation in case it comes back.

We have monitored the situation and confirmed that error rates have normalized. This incident is now closed.

Starting 2026-10-09T02:00Z we are experiencing intermittent connectivity issues towards our upstream provider for authorizations and voids (and Mastercard debits and debit refunds). Automatic failover and recovery is greatly alleviating the impact, but we have observed error rates of 0.75 % between 2026-10-09T02:00Z – 2026-10-09T07:00Z. We are investigating and reaching out to our upstream provider to resolve. Captures and capture refunds and Visa debits and debit refunds are not impacted.

Since 06:36Z we locked all traffic to our upstream provider’s secondary data center where we saw a lower error rate of ~0.04 %. At 07:42Z we were informed that the problem was resolved by our upstream provider. Since 07:53Z we moved traffic back to the primary data center and have seen no further errors.

We are closing this incident as no errors have been observed since 06:36Z and since the problem is confirmed to be resolved. An average failure rate of 1.14 % was observed between 2026-10-09T04:01Z and 2026-10-09T06:35Z (of when the first and last error occurred) with a peak error rate within a minute of 31 %. Additionally, we also observed a small collection of errors 2026-10-08T22:32Z – 2026-10-08T22:41Z at an average failure rate of ~11 %. Correction on affected transaction types! Authorizations, voids, capture refunds and Mastercard credits were affected. Remaining transaction types (captures, debits, debit refunds, and Visa credits) were not affected.

Between 2026-08-27T00:30:35Z and 2026-08-27T00:48:01Z, all Visa authorizations failed with status code 40400, "backend problem". A few Visa transactions were failing already starting 2026-08-27T00:25:25Z. Mastercard authorizations along with all captures, refunds, voids and credits were unaffected. We have seen no further connectivity errors since 2026-08-27T00:48:01Z. Failed authorizations were not charged and can be retried. We are working with our upstream provider to determine the root cause and to prevent similar issues in the future.
