KAREN, a network that provides high speed broadband to New Zealand education and research organisations, has had its network capacity between Australia and New Zealand doubled from 155Mb/s to 310Mb/s.Research and Education Advanced Network NZ (REANZ) CEO Donald Clark says the upgrade is driven by strong growth in the use of KAREN’s international network by KAREN Members.The additional service will be provided without a cost to the members. “The fact that we are having to make this upgrade in international capacity ahead of schedule is a strong sign that the KAREN community is leading the charge in developing the weightless economy New Zealand needs to survive,” says Clark.The upgrade in capacity will be provided by REANZ’s existing network partner, Verizon Business, and will be in place shortly.
