A well-known compute cluster at Berkeley created hostnames after types of disasters:

  -tsunami
  -apocalypse
  -famine
  -avalanche
  -hailstorm
  -lightning
  -heatwave
  -locusts
  -tornado
  -fallingrocks (<-- my favorite)
  

Interestingly, though run on a shoestring, this proved to be one of the most reliable set of servers on campus. I guess the disaster naming was a sort of a reverse jinx.
