The shortest "wire" was thousands of kilometres long. From a networking 
POV, that's not good.

I'm only an ignorant user, I don't know how the Centos organisation 
works or how you found the systems you do list.

I'll ask the two I've found.

As I already said in this thread, I do.

They're in this thread.

I've been using the Internet for quite a few years; when I was learning 
its ins & outs, I read that one should choose a mirror that is 
relatively local (as measured by the wire).

There aren't that many wires out of Perth, and they're very long ones, 
so from our perspective geographic locality and topological locality are 
pretty much the same.

Use of mirrors on the opposite side of the globe when there's a nearer 
choice just goes to tie up bandwidth needlessly, increasing costs for 
all. It's a bad idea.

I don't know the current position wrt international data flow, but I'm 
thinking Australia pays for incoming data. There was a big fuss years 
ago, the US wanted to charge Australia for data from US to Oz, but not 
pay us for data Oz to US.

There were several other mirrors listed, so there were other mirrors

It wasn't apparent to me that any of the mirrors I saw in the list was 
dedicsted to CentOS, and I suspect some are shared with other mirrors.
