> Ec2MultiRegionSnitch was (probably) done because it was not possible in AWS
> to have intra-region VPC peering. This changed pin 2017, see [AWS
> announcement|https://aws.amazon.com/about-aws/whats-new/2017/11/announcing-support-for-inter-region-vpc-peering/]
> (and extended with 9 more regions in 2018, see
> [link|https://aws.amazon.com/about-aws/whats-new/2018/02/inter-region-vpc-peering-is-now-available-in-nine-additional-aws-regions/]):
> {quote}Inter-Region VPC Peering allows VPC resources like EC2 instances[...]
> running in different AWS regions to communicate with each other using private
> IP addresses, without requiring gateways, VPN connections or separate network
> appliances.
> {quote}
> Since the datacenter/rack names are loaded in Ec2Snitch using AWS API there
> is no reason why this snitch would not work in a multi-datacenter setup. I
> tested and used this in a production environment. So the documentation should
> be changed to include this usage.
