Summary
The article discusses how AWS's recent DNS-related outage may be linked to a 'brain drain' of senior engineers leaving the company, taking with them decades of institutional knowledge about how AWS's complex systems work. The author argues that when experienced engineers depart, critical operational knowledge about fundamental infrastructure like DNS is lost, leading to preventable outages that should be avoidable for a cloud provider of AWS's scale.
