Example 2 - Roadrash
Technical Description:
This type of distributed denial of service (DDoS) occurs when there is too much traffic preventing client computers in different locations from reaching a similar destination server.

Real World Example:
A common scenario can be used for this situation. Imagine drivers as they approach an full parking lot. Vehicles drive up and down the aisles looking for an available parking spot. Some people even leave due to being unable to park.

Geekinese Translation:
There are several similarities between the two situations. In both cases, we have sources coming from different locations and arriving at the same destination. However, the parking facilities are unable to handle all of the traffic. The drivers and computer users are unable to reach their desired destination. As a result, services are denied to the people.
