I commented about Failure Fridays at PagerDuty in the older thread (not Chaos Monkey precisely, but similar concept). We still do that, with a few modifications: 1) ChatOps is used to execute the commands from Slack in order to preserve history and help interested parties follow along. 2) If we're not testing a specific service/AZ/region, a "reboot roulette" bot is run that reboots any host from our production infrastructure at random. Every single production host is game. 3) This is now scheduled to run automatically at certain times of the week. Many of the things we do regularly used to be terrifying. They no longer are precisely because we do them regularly. That's the value of chaos engineering.
