[AusNOG] PPC-1 Experience?

[Chris Pollock]

Ah, just realised I should clarify this:

> PPC-1 is unprotected and has a single path from Australia to 
> Guam, no branching units or dual paths.

I meant to say, that there are no branching units being used for
branching.  There are a number of branching units installed in the path
for possible future expansion - off the coast of Sydney, Brisbane and
both sides of PNG.

Cheers,
