ZARC Domain Name System Outage

Occurred At: 2025-03-10 12:00:00

Over the past couple of days, the .ZA namespace has experienced extremely high traffic loads on our nameservers, impacting some of our users. This surge in traffic triggered our DDoS protection mechanisms, which, as part of their design, temporarily restricted some traffic to maintain overall system stability. The ZARC engineering team is actively monitoring the situation and has implemented mitigating measures to address the high nameserver traffic volumes, particularly on our US infrastructure.

We are pleased to report that service performance is now improving, and systems are returning to full operational stability. Our team will continue monitoring the situation closely to ensure continued service reliability and availability.

All co.za, web.za, net.za, and org.za nameservers are functioning optimally, fully synchronized, and handling stable traffic. No malicious activity detected on the US nameserver. DNSViz confirms all four nameservers are healthy and error-free.
