Subject: Connectivity Issue

Message:

Yesterday afternoon NZX experienced a volumetric DDoS (distributed denial of service) attack from offshore via its network service provider, which impacted NZX network connectivity.

The systems impacted included NZX websites and the Markets Announcement Platform. As such, NZX decided to halt trading in its cash markets at approximately 15.57. A DDoS attack aims to disrupt service by saturating a network with significant volumes of internet traffic. The attack was able to be mitigated and connectivity has now been restored for NZX.

NZX will resume normal market operations today, Wednesday 26 August.
