Network Engineer, may you be steadfast in this impetuous world step by step

No.1 amazing and weird Hospital

First, share a story about others.
The implementation of a project in a hospital is completed, but the customer reported that the network would be disconnected from time to time. The network engineer Mr. Li received the task and was responsible for handling the case.

After log analysis, it is found that the building's aggregation switch will be restarted from time to time for unknown reasons.
Xiao Li decided to observe for a few days and found that the device was generally faulty at night, when the load was low.
All links have been detected and there is no problem. Later I changed the device, but the problem still exists.

Xiao Li did not believe this evil spirit and decided to stay on site at night to observe and vowed to find out why.
That night, Xiao Li slept directly in the weak room on the floor, and there was a bed where doctors and nurses were on duty.
On the first night, the device was not restarted.
The next night, just in the middle of the night, when someone opened the door, Xiao Li was scared. The nurse mm who opened the door was also shocked.
It turns out that the nurse mm is on duty and will come to the data center to have a rest in the middle of the night.

Do you need to sleep when the machine room is so noisy?
The nurse mm replied: it was indeed a loud noise, but I had to unplug the power and plug it back the next day.
Xiao Li: Nana
