I accidentally rebooted the network switch for the entire third floor.
Internet disappeared.
Phones dropped.
About 70 employees immediately stood up from their desks like prairie dogs.
I had two choices:
Admit I clicked the wrong switch.
Become proactive.
I sent this message:
“Unannounced infrastructure resilience exercise currently in progress. Please continue normal operations.”
Then I waited five minutes and turned everything back on.
Service restored.
No data loss.
Nobody died.
The CTO replied:
“Love that we’re testing this stuff proactively.”
So I wrote a post-exercise report.
Objective: Validate employee response to unexpected connectivity loss.
Result: Successful.
Finding: Employees become extremely loud after approximately 12 seconds without internet.
Recommendation: Continue resilience testing quarterly.
My mistake now has a budget.
