New Zealand's stock exchange has been hit by a distributed denial of service attack on Wednesday morning which forced the exchange to go offline for about an hour.

The New Zealand Herald reported that the exchange had gone down at 11.24am local time (9.24am AEDT) on Wednesday and resumed operations at 12.20pm.

On Tuesday evening, the exchange could not operate during its last hour, due to a similar reason.

This outage happened as the exchange was approaching a record closing.

iTWire has contacted the New Zealand stock exchange for comment.

On Tuesday evening, Spark, which is the network service provider for the exchange, said in a statement: "This afternoon a Spark customer, NZX Limited, experienced a volumetric DDoS (distributed denial of service) attack from offshore, which impacted NZX system connectivity.

"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."

Spark was contacted this morning, but referred iTWire to the stock exchange instead.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
