The outage was caused by a device which control plane failed. While the New Zealand National network recovered in milliseconds, and Hamilton services or services relient on Hamilton continued to have trouble for about 10 more minutes until the device reset itself. All Hamilton based services then recovered other than those directly connected to that device, which took another 5 minutes to recover when the device reboot was complete.We will be investigating the root cause of the control plane failure with the Vendor and apologise for any inconvenience this incident may have caused. An incidenet report will be attached to this even in the next couple of days.
