Yes. I understand this. I wonder if I didn't word my thoughts very
I don't know much about how radio is run.
I recall thinking at the time "I wish they'd tone down the hype... this
is VERY real". It was my observation that the radio hype toned down
later in the day. I think you're right that the reason was they had
more concrete information to talk about. Reflecting on it later, I
wondered if they have a disaster policy? I wondered if they really
understood the impact they were having on people.
Perhaps my views are cynical. I know I turned to the radio for a sense
of comfort that afternoon. A feeling of being 'informed' while I
shovelled barrow loads of silt away, that rose up under my home, was
important to me.

Sorry, that was not my intention at all.
My impression is that these people were proud to do the job as best they
could. To me, a 'money shot' isn't just about how much they can push
the ratings, it's also about doing your job well to tell the story.
News guys are passionate about what they do. But they are human, and I
think we lost sight of that at one point in the weeks that followed as
one of our best started to crack.
I recall earlier in the year we had another disaster down here, a mine
exploded. It was a media feeding frenzie. But that's what it was, a
frenzie, none of the media were in any danger of getting hurt. But this
was very different. The media were in harms way. Frankly their
professional level was amazing to watch.

Yes. I now have an inverter permanently in my car so we can charge phones.

A growing number of homes have generators now as a result the the
quake. A number of my friends have generators now as well.
We are moving to an IP world, like it or not. That's how I see it
anyway. I like POTS, it's simple and will run over just about
anything, but it's expensive and my experience showed that it can't be
relied on as well as my VoIP.

My neighbour on the incumbent lost his service for 3 days when the sewer
guys damaged the lines and the telco simply wasn't able to get service
to him because they couldn't figure out what was wrong.
My other neighbour lost his pstn, and I suspect it was because of issues
in the city exchange that controls all the nodes. But what ever caused
it, it was down for days with no way to get calls moved in a cost

Fibre - "Sorry 6 weeks..."
Copper - "Sorry it's been 6 weeks... may be next week..."
Wireless - "After lunch tomorrow, but your phone calls might chop a bit..."
What's an 'SLA'?
What I will say is that the wireless option was a very useful tool to
get a hurry on sorting the copper services. ;)

If the price point is right then they might. But I suspect that the
price point is going to have to be right for many.

Agreed. It's no where near as simple as just digging a hole, pushing in
a fibre and knowing you can deliver 300Gbit without much effort, just
the right head ends.
> Wireless is a mixed bag, but it is indeed better than nothing.
100% agree with that. If you want your business back on line fast then
wireless is the only way to do it in my view after seeing what I've seen
in the past 6 months.
Having said that, the guys who I've been talking to locally about it,
are using a lot of fibre to aggregate data around the city. They're not
using long reach wireless, they're using it to do short hops and taking
care to manage resources carefully.
