Do you still have enlisted troops in the “Netflix Simian Army” (bots for automated testing)? If so, are there any new 'monkeys' you are using today, or have any of the original 'monkeys' been replaced or retired?
The monkeys live! I haven't heard of any new monkeys recently, but we've upgraded Chaos Monkey a number of times and continue to increase our failure injection initiatives. Speaking of which, the Chaos team recently released a free e-book through O'Reilly if this stuff tickles your fancy: oreilly.com/webops-perf/free/chaos-engineering.csp
