Simulating S3 Down

We can simulate AWS S3 being down by using iptables to drop traffic to the addresses it is hosted on, at least from an EC2 VPC host.

aws ec2 describe-prefix-lists

shows

{
  "PrefixLists": [
    {
      "PrefixListName": "com.amazonaws.us-east-1.s3",
      "Cidrs": [
        "54.231.0.0/17"
      ],
      "PrefixListId": "pl-63a5400a"
    }
  ]
}    

where we can pick out the network range and feed it to iptables

iptables -A OUTPUT -d 54.231.0.0/17 -j DROP
