So is this a good time to ask about the design of a network that concentrates so much of its core service in Auckland? Is TelstraClear's network design any better? How many regional providers were unable to talk to others in the same region because everything (?) is hauled back to Auckland? Does having Domestic Internet Service from Telecom and TelstraClear concentrated between these two "Tier 1" providers seem like a good idea? Does a network of regional Exchanges have any value? If TelstraClear had been peering at the Exchanges would their connectivity to Telecom's Tier 2 customers been disrupted as much? As Telecom customers you should demand answers about their failure of course but you also should be thinking about how you can have things in place to route round failures as well.
