Human Stories

The CloudFront VPC Origins outage reminded me that our biggest exposure isn't always the failure itself - it's being caught mid-transition when we've committed to a new architecture but haven't fully abandoned the old one. Reading about AI agents exploiting other AI agents and the AMOS stealer's social engineering tactics, I'm struck by how much of our security posture still depends on humans making good decisions under pressure, whether that's resisting the urge to paste Terminal commands or properly configuring multi-Region CMKs in IAM Identity Center. AWS rolling out Transit Gateway policy-based routing and Oracle interconnects shows the platform is maturing in exactly the ways we need, but those nine Cloudflare maintenance windows scheduled for August are a good reminder that even the most sophisticated infrastructure still requires old-fashioned coordination and communication. We build increasingly complex systems to solve yesterday's problems, and somewhere in that layering of solutions we create new failure modes that look nothing like what we planned for.
