Then there's this, from Facebook:

It's interesting, in light of the Productivity Commission looking to remove the USO 
for traditional phone services (landlines & payphones), that I see an article 
today that people in hardest hit area of the cyclone are scrambling to use the 
payphones as no other communication is working.

Duh.
I meant kU band. I don't know what is happening to my head! I think I have this 
right now. We went from C to Ku. This was in the US when we were doing a lot 
more with narrowcasting via satellite for distance ed purposes. Here's the Ku 
article, and you'll see the proliferation of Ku satellites.

I was going to mention weather impacts. Back in the day of Ka band, which 
replaced C (the bigger dishes we used to grab signal from early satellites), 
rain was an issue. Lots of noise. I didn't know if it continued with Ku or not.

I've seen a post from someone in the danger zone who'd managed to power 
their Sky Muster S-NTD with a genset, but couldn't get signal. How much

The other common NBN option in the regions is fixed wireless. They 
started off with the 2.3 GHz band. That doesn't play well with 
vegetation (or rain, apparently). I've seen images of devastation as 
farmers try to clear a line to get signal. Now, they've moved on to 3.4 
GHz, which works worse. Of course, our government is still selling off 
700 MHz spectrum to the highest bidder. Never let vital infrastructure 
get in the way of a quick dollar.


Meanwhile, in the town of Cessnock and surrounds, I notice workers 
running out black cable. I presume that's copper.


And those blasted ads still come up far too often on TV. >:(

[LINK] Internet of Malware comes to Miele dishwashers

[David Lochrin]

Something to smile about, or possibly cry about:
https://www.theregister.co.uk/2017/03/26/miele_joins_internetofst_hall_of_shame/

A Miele commercial dishwasher can apparently be hacked very simply using the 
old directory-traversal trick.

This appliance includes an embedded web server so it can be controlled from a 
browser, and that brings to mind the thought that many IOT devices must do so.  
So how are they secured?  Is China even now working out how they can disrupt 
life as we know it by disabling pub dishwashers?
