Tools
Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets. Very handy for testing distributed systems under non-ideal network conditions.

Toxiproxy is another tool for simulating network errors for testing purposes. It provides a proxy with an API, which allows for altering the network conditions cleanly. The example gives you a great idea of what’s possible.
