title: More than 1 subnet per AZ for AWS Interface Endpoint?
body: <p>Can I supply more than 1 subnet per AZ to create an AWS Interface Endpoint?</p>
  
  <p>When I tried, I got this error:</p>
  
  <pre><code>Error creating VPC Endpoint: DuplicateSubnetsInSameZone: Found another VPC endpoint subnet in the availability zone of subnet-xxx. VPC endpoint subnets should be in different availability zones supported by the VPC endpoint service.
  </code></pre>
  
  <p>My VPC is set up such that there are multiple subnets per AZ. Does this mean that instances set up in a subnet that doesn't have the VPC endpoint network interface will not be able to access to AWS service?</p>
