The root cause was IP address exhaustion: a query plan change overloaded the control plane database, preventing database suspensions, which caused ~8,000 pods to run simultaneously and exhaust available IPs in two of three subnets. Mitigation involved reconfiguring AWS CNI WARM_IP_TARGET settings, upscaling the control plane database, and enabling rate limiting at the proxy layer. A second outage on Monday was triggered by reverting those CNI changes. Short-term fixes include doubling VPC subnet sizes and prewarmed compute pools. A longer-term architectural overhaul called 'Cells' is in progress to address underlying Kubernetes scaling limitations. ## Full article daily.dev links to this article rather than hosting it.
