There are quite big differences btw the scenario where they blew up nodes 
( the backup set of nodes was in full operation and just needed to take 
conrol ) and this one.

In this specific case the whole servers as data on the disks ( os + 
application ) is kept mirrored offline to a remote location.. but it's just 
that... there are no live servers there. The servers are created  ( vmware ) 
in those 90 min , including an orderly boot of each one to ensure that the 
environment goes back up, from the last "good" set of data.
Meanwhile 30 minutes are needed to reroute the network traffic, in parallel.

It's a totally different scenario : imagine to boot up 17 or 19 servers, 
with the need of follow also a specific order....
