Keep in mind that the highly sought-after bosses are scouted regularly. The only time I've found Gubakoo or Kipeeketh on my own was when the server was literally empty, i.e. when it's morning in Europe.
I'm not sure if the next respawn time is assigned right after the kill, or it's just a random roll. What I do know is that boss spawns are done at certain intervals (can't remember if 30 minutes or two hours).
Oh, not to mention that some rumors say multiple bosses of the same level tend to spawn at the same time. If you find Cuttlekin, you should go check all lvl 200 regions.
