Root Cause of the System Disruption
The downtime was caused by an unexpected technical fault within a core infrastructure component. Servers supporting this component experienced a sudden and abnormally high transient load. This surge was triggered by a specific log process, which led to the exhaustion of critical system resources.
The failure of this core component subsequently rendered downstream trading systems incapable of processing certain user requests. To prevent market disorder and protect user assets, a global suspension of all trading services was implemented while the technical team applied a fix.
