The problem with tech support

The problem with tech support apart from the users creating problems left, right and centre is that occasionally something important goes wrong. On those days you do not want to be the first techie in the office.
So this morning I was on the early shift. I arrive at the office to find all of the machines down. I won't go into too much depth about the technology we use but all of our machines run from one server. In fact there are two servers just in case one goes down. So I arrive and all the machines are down. This either means that both servers have gone down overnight (quite unlikely) or that something more fundamental is wrong.
I call Cliff (the systems guy) since I don't have a clue where to even start fixing the problem and he tells me not to touch anything since it sounds quite serious and he will be in shortly.
Ten minutes later he arrives and I get a call asking what the first thing I should do when I arrive in the office is. Apparently (although its the first I have heard about it) I am supposed to check the server room when I arrive to make sure there are no obvious problems. Having been told by Cliff not to do anything at all I fairly obviously hadn't checked the server room. If I had checked the server room I probably would have noticed that the air-con had packed in and that our server room could now double as a sauna.
Fortunately everything seems ok now although I am slightly concerned that I might get in trouble for not knowing about checking the server room every morning...
