I think it's relevant that Baron's post mentions a Github incident, and Github has been doing automatic failover of MySQL masters for a while now: https://githubengineering.com/orchestrator-github/ https://githubengineering.com/orchestrator-github/ This post is also very relevant to the topic: http://code.openark.org/blog/mysql/mysql-high-availability-tools-followup-the-missing-piece-orchestrator http://code.openark.org/blog/mysql/mysql-high-availability-t... The post you link is still relevant to this discussion, but we can't ignore that 5 years have passed. It would be good to see 2017's Baron revisit the topic :)
