New Zealand’s third largest telecom went offline for almost an hour earlier today reportly due to a cyberattack.

According to Kentik aggregate NetFlow data, internet traffic to and from Vocus NZ (AS9790) stopped at 1:20 UTC (1:20pm local) and didn’t begin to recover until 2:06 UTC. It wasn’t until 2:25 UTC (2:25pm local) before traffic levels had returned to normal.
