In a statement with NZ telecommunications company Spark, the NZX said it has confirmed the network went offline for approximately one hour today following a second attack on the exchange.
“NZX confirms that it is working with its network service provider to address a further issue today, impacting NZX system connectivity,” it said.
The first attack halted trading on the NZX at around 3.57pm as the index closed in on a new record.
The S&P NZX50 market closed to its all-time high of 11,993.18 points, up by 72.10 points or 0.6 of a percentage point.
“It appears that this is similar to yesterday’s issue. NZX halted trading in its cash markets at approximately 11.24am,” it said.
“NZX’s network provider continues to investigate the source of the issue.”
The stock exchange experienced a “volumetric DDOS (distributed denial of service)”, which aims to disrupt service by saturating a network with significant volumes of internet traffic.
Today, the NZX opened this morning and traded for about an hour before coming to another halt at 11.24am local time.
More to come.
