Account vCPU quota exceeded
A routine autoscaling event during evening peak fails: new EC2 instances launch but stay `pending` then terminate, and your ASG activity log shows `Could not launch On-Demand Instances. VcpuLimitExceeded` for your instance family in us-east-1. Meanwhile pods elsewhere on EKS are stuck `ContainerCreating` with `failed to assign an IP address to container` in the kubelet logs. Traffic is up 40% over a normal Tuesday because of a marketing email that went out at 18:00. How do you triage this and restore capacity?

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
