....Keeping Vocus going at Albany would be easy. The main problem will be customers out of electricity.

....Vocus Albany has diesel generators and 3 fibres in so can stay on-line through most disasters [other than right there on site].

That info could do with an update..

Power is 2N end-to-end, ie supplied from diverse: substations, underground cables, transformers, switchboards, generators (x3), in line UPSs and, power distribution right down to the A and B PDUs in the racks. (HA Colo)

Cooling system is also 2N with a double cooling loop and a rather large tank of chilled water in case something truly unfortunate happens.

Isn't the cooling water all linked so in the unlikely event that a major leak happened (Someone put the car into drive instead of reverse in the carpark... driving into them thar pipes), the cooling would totally die apart from the DX units?

MauriceWinn: A risk in Auckland which is never mentioned anywhere is that Auckland is going to lose the Waikato River some time. That means Auckland will lose nearly all electricity and much of the water supply [which is taken from the hills around Auckland but also from the Waikato river].

The central volcanic region is a catastrophe waiting for the day when the magma chambers are reloaded enough to overcome the downward pressure. There is a 1:10 chance of Taupo going up in any lifetime. That's a risk too high for me, but hordes of people live within the death zone with huge property investment.

Neither is it a low risk with time to evacuate if there are lots of rumblings. Taupo is a colossal geyser type volcano which goes bang in minutes and hours rather than over days and weeks [which the scoria cones of Auckland do, after much rumbling as magma slowly rises].

Maxnet could keep diesel supplies for electricity with imports from the pipeline from Marsden Point so service could be uninterrupted. Diesel supplies would probably be adequate as there would be greatly reduced demand for diesel for road transport with the southern motorway shut due to Waikato River basin destruction.

Christchurch has a bit of a problem at present, but it's trivial compared with the scale of Taupo blowing.

Auckland should have a nuclear reactor, or thermal power station using coal.

CO2 emissions are not a problem, contrary to the current fears about Global Warming. CO2 at 500 parts per million is a good thing, not a bad thing, and it will take 100 years to get to 450 parts per million. Reglaciation starting in 2020 is a more likely risk than Global Warming, and the south island is going to be a cold place again.

NZ depends on crops growing. With more CO2, crop production goes up. Farmers buy and burn carbon to provide CO2 and warmth to their glass houses.

I do believe that NZ can't handle current-technology nuclear power plants, not because of the cost but because they would produce too much power, putting strain on the infrastructure and creating to much of a single point of failure in that if it went offline, there would be no way for other facilities to take up the slack.
However I understand nuclear power technology is developing so it's easy to build smaller more cost effective plants. But then you would need to change the mindset of NZ's anti-nuclear stance. Good luck.

Regards the Waikato - I don't see how that is a problem. You can't honestly think that Auckland solely relies on Huntly power station for it's power - especially with the Whakamaru line coming online soon.

"Much" of it's water supply is a bit.... much. Don't forget we survived fine without it until that drought in the 90's.
Here, Ill even provide a reference...something missing in your post.

8% ... I think we would cope if it went away. Especially given that such an event would be a long time coming, giving authorities time to come up with alternatives.

There are two independent water loops, mainly used for HA colo, you've found only one of them :) . They can be linked for maintenance etc if needed.

Premium and Premium Plus uses a combination of water and DX.

It's not just Huntly power station affected by the Waikato river being destroyed by the next Taupo eruption. The Tongariro and other hydro-electricity and geothermal supplies will all be pumiced. No electricity will be going to Auckland from the Waitaki or other south island supplies either, as the cables will be gone.

Thanks for the accuracy on water supplies from the Waikato. 8% isn't much at all and can be replaced overnight by a price increase to get people to cut water usage, as expected. I had guessed it would be perhaps 30% by now and in drought conditions it probably is. Designing supplies to cope with droughts is a good idea.

Whether nuclear or thermal, a power station near Auckland is a good idea because losing all supplies from over the Bombay hills will be a disaster for Auckland. It won't be so good for people south of the Bombays either, but survivors would head north for the bright lights of the big city.

China's nuclear reactors: http://www.world-nuclear.org/info/inf63.html They should be able to supply one easily enough at a good price: <<

Mainland China has 14 nuclear power reactors in operation, more than 25 under construction, and more about to start construction soon.
Additional reactors are planned, including some of the world's most advanced, to give a five- or six-fold increase in nuclear capacity to at least 60 GWe by 2020, then 200 GWe by 2030, and 400 GWe by 2050.
China is rapidly becoming self-sufficient in reactor design and construction, as well as other aspects of the fuel cycle.

If Taupo blows North islanders just need to leave NZ. NZ will become the South Island.

It's not that bad: <<If Taupo blows North islanders just need to leave NZ. NZ will become the South Island.>>

Taupo is like a geyser except that it's big and made of pumice instead of water. It isn't a mater of if, it's a matter of when. When it goes off, again, regularly, as it has done for a very long time, it will be fine to live in Aukland apart from there being no electricity, which is easily fixed now - build power stations. Keep the data centres running, and a lot more besides.

The initial propulsion method is the same as a geyser. Liquids turn to gas when the pressure is reduced enough and enough upward pressure is developed to launch. So Taupo will erupt on a full moon, during a low lake level drought. The liquids in pumice turn to gas, giving that very light fluffy rock when it freezes while flying through the air. Like Edmonds baking powder Taupo is "Sure to Rise" and the pumice will be nice and fluffy, like a light sponge cake.

The trout will be well-done.
