DDoS attacks hit servers with increased incoming connection requests that overload the servers and effectively block legitimate requests.

Around lunchtime last Friday, Kiwi internet provider Vocus NZ, which owns the Orcon, Slingshot and Stuff Fibre brands, crashed following a cyberattack on a customer that impacted on services and the company sought to respond to the hack. The issue also disrupted Sky TV, a Vocus NZ client.
