Core API Degraded Traffic

On Tuesday, July 21, 2026, Marqeta experienced a traffic flooding event that led to service degradation across our API infrastructure. This volume triggered automated protective measures, causing intermittent instability for several services. Our engineering teams have successfully mitigated the issue by migrating the affected endpoints to isolated infrastructure to shield our core services and ensure load is managed effectively. We have confirmed a return to normal service levels across all of the impacted services, and we are maintaining proactive monitoring to ensure continued platform stability. We appreciate your patience as we worked to resolve this incident.

Marqeta engineers successfully completed primary remediation efforts at 13:35 PDT, resulting in a significant reduction in service impact across our platform. Our infrastructure has stabilized, and services are recovering. We are continuing to monitor system performance closely as traffic patterns normalize and are proactively implementing further architectural optimizations to ensure continued reliability. We will provide a final update once we confirm full service restoration and stability.

On Tuesday, July 21, 2026, at approximately 12:19 PT (19:19 UTC), Marqeta engineers detected an issue causing intermittent service degradation and elevated error rates affecting multiple services. Our engineering teams initiated a mitigating action at 12:45 PT (19:45 UTC) as a part of our ongoing remediation efforts. We are actively provisioning the fix and will provide a follow-up status update once the fix is completed and verified to ensure full service reliability.

We are continuing to work on a fix for this issue.
