Your machine, or anyone's machine? Remember to multiply a network failure by the number of people if you're doing that kind of comparison.
Also, get better machines. The last time a machine failed at this all-macbook shop was several months ago.
That's your privilege. I don't. The only time I remember the network going down was after a complete air conditioning failure in the server room (a highly unlikely event in itself, but not IMPOSSIBLE) which forced a complete shutdown of IT services. And even then people could still work. Sure, not as well as usual but working was possible. The last time a machine failed was .. oh right. Yesterday.
