- postmortem Aug 11, 2026, 07:17 AM UTC
On 10 August 2026, card payments were unavailable for approximately 46 minutes, between 09:58 and 10:44 CEST. During this window, customers were unable to complete card payments. The disruption was triggered by a planned database update that generated an unusually high volume of background events. This event volume placed excessive load on several of our Card Acquiring services, including the component that processes card transactions, causing them to become temporarily unavailable. Tap to pay transactions continued to be processed, but were briefly delayed in appearing in our Buckaroo portals. Our engineering team identified the root cause and deployed a fix that restored the affected services. Card payments were fully operational again from 10:44, with all services confirmed recovered at 10:49. We have implemented immediate safeguards and are working on structural improvements to prevent this failure mode from recurring. We apologize for any inconvenience this may have caused.
