Overview of the Incident

The market’s ability to function was severely compromised, with traders encountering obstacles that left them unable to execute trades effectively.

Broader Implications

The duration of the outage raised concerns about the resilience of financial markets and the robustness of critical infrastructures. The incident highlights potential vulnerabilities in trading systems that can have far-reaching consequences for global finance.
