We are currently experiencing a large-scale DDoS (Distributed Denial of Service) attack targeting one of our servers. Our DDoS mitigation platform has automatically detected the attack and traffic is currently being routed through our scrubbing infrastructure to filter malicious traffic and maintain service availability. While mitigation is active, some services hosted on the affected server may experience intermittent connectivity issues, increased latency, or brief disruptions as traffic is analyzed and scrubbed. Our engineering team is actively monitoring the situation and working to ensure continued service stability. We will provide further updates as the situation develops. Thank you for your patience and understanding.
