Alex dug into the VM’s birth certificate (a metadata endpoint they used for auditing). The VM was provisioned — impossible, because Netflix autoscaling recycled VMs every 14 days max. But then: Alex dug into the VM’s birth
Then came the really weird part. Because the VM never recycled, its local SSD (ephemeral) had accumulated — normally deleted every week. The ML training pipeline saw this "ancient" VM as a stable node and started preferring it for critical A/B tests. By December 23rd, 3% of all北美 traffic was being routed through this single zombie VM.
