Re: Physical security of server room ?
"Someone pulling a stunt like this would have been rumbled in hours."
$32K, over three years. Doesn't say how many servers were affected. $32K could be $31K in lost business / cost in man-hours to bring systems back online, and only $1K in physical hardware... maybe two cheap servers. Maybe $16K in costs and $16K in hardware, which could mean just three servers were destroyed.
You're not going to suspect the first one. Server died, you get it swapped out, you don't even question why it died. The second, a year later, you *might* say "hmm, that's the second server in two years, I wonder if there's a manufacturing defect?"
Third one in three years makes you curious so you check the video. Of course, you don't have the videos from a year ago much less two. But yes, you immediately spot someone who shouldn't be there.
So, yeah, it's possible that you find it quickly, but only if you've got a reason to suspect that it wasn't just random hardware failure. Which depends entirely on how many servers were going down and how often.
