24 Situations like these that made me decide with great conviction to always
25 deploy my servers virtualized, even if the box in question will only host a
26 single VM.

28 Now, if I lost my intelligence for a couple of seconds and somehow ended up
29 with a VM that's no longer accessible remotely, I just connect to the
30 virtual console.

32 The flip side? Now I'm getting too daring/careless, and the uptime now
33 drops below my (self-imposed) target of 99.99% :-P
