KuCoin UTA-API upgrade Aug 27, WebSocket changes postponed

KuCoin will run a zero-downtime upgrade to its UTA-API beginning at 06:00 UTC on August 27, 2026, expected to last about 120 minutes. During the window, the UTA WebSocket may experience temporary disconnections, data loss, or delays. KuCoin has since postponed the WebSocket changes originally scheduled to go live on August 27, 2026, at 06:00 UTC, following further evaluation to ensure the stability and compatibility of the UTA API updates.
