+Comcast
+=======
 
 Testing distributed systems under hard failures like network partitions and instance termination is critical, but it's also important we test them under [less catastrophic conditions](https://www.bravenewgeek.com/sometimes-kill-9-isnt-enough/) because this is what they most often experience. Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets.
 
 It works by wrapping up some system tools in a portable(ish) way. On BSD-derived systems such as OSX, we use tools like `ipfw` and `pfctl` to inject failure. On Linux, we use `iptables` and `tc`. Comcast is merely a thin wrapper around these controls.
