It is funny to think about the reality of a lights out data center, Dilbert Cartoon as an example

Dilbert has a cartoon on lights out data centers.

Human error in the data center is a reality, and the funny part is an answer just like above is to not allow employees in the data center.  Especially if the data center is self-aware.

What is potentially worse than employees are the vendor support employees who are not tracked.  Do you exactly what the warranty service technician did in his service call in your data center?
