Network 404 Secret Control And Government Vehicle Developmental Center 1886

Network 404 is a government network that processes things no one knows about. A few top secret files were taken very recently and cannot be understood.
For instance this picture taken portrays strange symbols. The text seems either computer generated or alien. And the way the image is arranged seems unlike the way a normal person would write a letter to another planet. Some of the symbols can be recognized but not understood. Nothing is known about Network 404 to this day...
