RE: Never push the Big Red Button (New York City subway failure)

[Matthew Huff <mhuff () ox com>]

Since we are telling power horror stories…


How about the call from the night operator that arrived at 10:00pm asking “Is there any reason there is no power in the 
data center?”

Turns out someone had plugged in a new high end workgroup laser printer to the outside wall of the datacenter. The 
power receptacle was wired into the data center’s UPS and completely smoked the UPS. Luckily the static transfer 
switched worked, but the three mainframes weren’t’ happy…


Or

Our building had a major ground fault issue that took years to find and resolve. We got hit with lightning that caused 
the mainframe to fault and recycle…and two minutes in, we got hit by lightning again. When the system failed to start, 
we called IBM support. When we explained what happened there was a very long pause…then some mumbling off phone, then 
the manager got on the line and said someone would be flying out and be onsite within 12 hours. We were down for 3 
days, and got fined $250,000 by the insurance regulators since we couldn’t pay claims.

True EPO story; maintenance crew carrying new drywall into the data center backed into the EPO that didn't have a cover 
on it. One of the most eerie sounds in networking...a completely silent data center.

Reminds me of something that happened about 25 years ago when an elementary school visited our data center of the 
insurance company where I worked. One of our operators strategically positioned himself between the kids and the 
mainframe, leaned back and hit it's EPO button.

Or when your building engineering team cuts themselves a new key for the 'main breaker' for the facility... and tests 
it at 2pm on a tuesday.
Or when that same team cuts a second key (gotta have 2 keys!) and tests that key on the same 'main breaker' ... at 2pm 
on the following tuesday.

<quadruple face palm>

not fakenews, a real story from a large building full of gov't employees and computers and all manner of 'critical 
infrastructure' for the agency occupying said building.
