On June 2, 2026, some customers experienced elevated latency on /v1/issuing/risks and /v1/customers requests in prod-eu. We’re sorry for the disruption and for any delays this caused in customer risk decisions.
A subset of issuing risk requests became slower than expected due to delayed customer data lookups. During the main impact window, affected requests could take up to approximately 5 seconds before continuing through a soft-fail path.
The issue was caused by a customer lookup path not enforcing its intended short timeout. When some customer lookups stalled, they waited on the broader request deadline instead of failing fast at the operation-level timeout.
We deployed a hotfix to reduce the customer-load timeout and limit how long issuing requests can wait on stalled lookups. We are also adding follow-up improvements to reduce Datastore dependency in low-latency paths and investigate the underlying cause of the lookup stalls.
