[AusNOG] Zettagrid Sydney Offline

[Shane Short]

What about on different continents? There could be some kind of 
catastrophic act of god that wipes out both facilities? Oh.. separate 
hemispheres too, to protect you against freak storm events..

Maybe we should co-lo on the moon too, incase there's some kind of 
catastrophic earth event.. but even then we still have single point of 
flares (SPoF) to contend with.. mmm

At some point you play the odds. How many times has the aforementioned 
"global fuckup" happened?
