Ha. Yeah thats why we were once known to the British as "The Shaky
Isles" . We do have lot's
of earthquakes around the pacific rim. We are in Auckland however which
is north of all those little stars on the pic
which is where the edge of the pacific plate intersects with the
Australian plate. So not too many earthquakes
to worry about in Auckland compared to the rest of NZ. Although one of
the data centers I built recently
was on the second floor of a building and had to be earthquake
restrained due to the fact that we were going
to be potentially creating up to one ton point loads on the floor. The
rest of NZ gets little and biggish quakes
fairly often, so much so that the Aussies next door on the west island
see fit to warn their citizens about the
potential for earthquakes in NZ if visiting... Our capital city
Wellington the other hand is built on fault lines.. think
San Francisco...
Now a Volcano in Auckland might be a different story... We have over 50
dormant cones and whopping big one in the
main harbor which is called "Rangitoto". Translated form the Maori it
means "Blood Sky". My UPS's wont
protect from that one...
;)
I am far, far more worried with someone with root access typing
'zpool destroy' than I am worried about the lights going out in the
data centers I designed that house hundreds and hundreds of servers. ;)
Yeah, this is probably more likely.
