UPS
They're a bit like having a guard dog that is high-maintenance, sleeps through a fraction of the burglaries, makes a huge mess once a week, and every once in a long while eats one of the children.
I've been evacuated from the workplace several times BECAUSE OF the smoldering UPS.
Not to mention the other times they've malfunctioned, shutting down the server without notice.
Supposed cure, which it often isn't, that is often much worse than the disease.
I hate them.
Biting the hand that feeds IT
