Well, I now feel like a schmuck...I may have got someone in trouble that may or may not have done anything.  I think they did...but I didn't actually see them do it, I just pieced things together and drew a conclusion.  The worst part of it is, I told my boss this and he sent a nasty email out because of it.  I was at the datacenter tonight installing a new storage array, as I was finishing the cabling I was laying on the floor I could see through our rack and saw that someone was doing something on the other side.  I could only see them from the waist down, but as the person walked out of view a second or two later he was at my feet.  I didn't pay much attention, I just tried to move out of the way so he could pass, I kept cabling.  As he passed me by he said "I'm sorry, I'm just doing a rack inspection".  I didn't think anything of it, I kept on going business as usual, finished up cabling and when I stood back up I noticed the little blue reminder light was out...this wasn't anything startling as it frequently comes unplugged.  I tried to plug it in again only it was plugged in all the way.  I looked closer and noticed that the network lights were out also...that means the server is off...something made me look at the cable management arm and I pushed it back a little bit and, low and behold, the power cables had both been yanked out.  I quickly pushed them back in and the server jumped to life.  So I then started replaying what just happened and pieced everything together and realized that the "I'm sorry" must have been because the guy bumped the protruding cable arm innocently.  When I called back to the office to let them know what I thought had happened, I made my inferences sound like fact.  I wouldn't have thought any more about it, but Colin sent out a nasty email to the data center demanding to know who the guy was and informing him that he'd be sending him the bill for the overtime costs.   At first I thought it was funny, but as traffic was so backed up due to rain I had nothing but time and my thoughts I started playing out different scenarios and am now wondering if that guy did it at all...I know I heard the "I'm sorry" but maybe he bumped me..or the rack or was saying it because he had to sort of step over me.  I was, after all, running the SCSI cable through the cable management arm..maybe I unplugged it...I'm always extremely careful around the hardware, but even I make mistakes...did I make this one?  I guess I just feel guilty that someone else is gonna get in trouble, but perhaps more so because I accused them with out knowing for sure if they even did something wrong...guess I'll have to see how this plays out.
