[Tokyo, Ap03 and US Regions] Performance degradation with Bulk Load, Bulk Import and Result Export jobs
Resolved on July 27, 2026, affecting Data Connector Integrations and Data Connector Integrations and 1 more.
Between 7/25 and today, 7/27 at 11:30 AM JST, we experienced a performance degradation issue affecting BulkLoad (Data Connector Import), Result Export (Activation) and Bulk Import. Following reports received this morning, our engineering team investigated the issue and identified high system load under specific conditions (increasing delay in internal components communication) as the root cause. The issue has been resolved by full rotation of our server nodes, and full performance was restored as of 11:30 AM JST. We sincerely apologize for any inconvenience caused. We are currently reviewing our monitoring and alerting rules to prevent similar issues in the future.
