Henny Penny fryer has many additional opportunities to reach the server successfully.
The downside is if our signal is blocked by a structure (i.e. wall, distance, etc.) and is

of failure. As an example, if the signal is being routed through a refrigerator (node)
and not directly connecting to the server, then the refrigerator becomes a point of
failure.
