The following recent Youtube video depicts a montage of "scary networking fails [and] real-world networking problems."
The video was produced by Discount-Low-Voltage.com, the e-commerce division of Cable & Wireless Technologies, Inc., a wholesale distributor of low voltage products, tools, testers, and other devices for telephone, computer network, home theater, commercial sound, video surveillance/CCTV, and other types of low voltage installations.
"This is what happens when your network gets out of control," writes the company.
