   Between 2026-05-20 17:57 UTC and 2026-05-21 01:44 UTC, a subset of customers operating in the AP-NORTHEAST-1 region experienced intermittent HTTP 5xx errors impacting object storage operations. The issue was triggered by failures on a portion of the underlying storage hosts, resulting in temporary service instability within the region. The host failures occurred under elevated internal system activity associated with platform health-management operations and concurrent storage reclamation workflows. Service impact was intermittent throughout the event window. Wasabi has implemented additional operational safeguards and recovery workflows to accelerate remediation of impacted internal nodes. These enhancements improve recovery efficiency across high-availability infrastructure and further reduce the risk and duration of future service-impacting events.
