Is your Internet slow?
If you are having a problem with your internet, e.g. slow, and you think there is something wrong with your end. This NZ site allows you to check your provider, e.g. Spark or Vodafone.
This example shows Spark had real problems between say midday and 10 pm and BNZ shows spikes at 8 pm and 11 am during their period. These graphs are examples only and dynamically updated,
