Microsoft Exchange of fluids
During my sandwich degree some years ago, I was working on placement in an IT department at a very well known and quite large national mapping organisation in Southampton.
While there, I started courting a colleague... I say courting, I mean nipping back to hers at lunchtime for a quickie. When time was short, on a couple of occasions we made use of the deserted and usefully-chilled server room - don't panic, she had her own access, I wouldn't breach security, what do you take me for?!
Anyway, on one horny occasion we nipped in there, and after doing the deed, in the process of pulling my trousers back up, I stepped back onto an extension cable carelessly and unprofessionally draped between racks, tugging the plug out of the socket (for the second time that day, arf arf), and cutting the power to the entire rack, which most vitally included the Exchange server for all 4000+ users.
Hearing the sound of banks of fans and drives spinning down, a wave of dread washed over me as I sensed something had gone horribly wrong. Given the compromised position we were both in, my now-wide eyes looked over at my bae silently communicating "oh fuck", and I proceeded to evacuate my face entirely of blood.
Once the panic subsided, I quickly mashed the plug back into the socket, and we quickly but outwardly-calmly exited the room, straight past our support phone monkeys who, unbeknownst to them, were about to suffer an influx of incoming calls in 3....2....1.
Anon, because to this day only me and her know about this. Oh, and you ugly lot. And maybe the CCTV guy. Actually, I should probably check Pornhub.....
