Situations like these that made me decide with great conviction to always deploy my servers virtualized, even if the box in question will only host a single VM. Now, if I lost my intelligence for a couple of seconds and somehow ended up with a VM that's no longer accessible remotely, I just connect to the virtual console. The flip side? Now I'm getting too daring/careless, and the uptime now drops below my (self-imposed) target of 99.99% :-P Rgds,
