Re: Every single time
Had that happen at Big Insurance Company - a manager found a set of aircon controls that he didn't know about before so did the only rational thing and turned them all off. Turns out they controlled the aircon for a nearby (locked) room that had jump box PCs for the offshore support guys to remote onto so they could establish local sessions with user PCs. I found out about the existence of this room cos' I was tasked to go in and reboot one that was playing up, opened the door and was met with a blast of heat from 100-odd PCs running in a shoebox with no ventilation anymore...
