Yes and no. You can use it, but with latency the only way to specify the location of your servers is by relating them to a AWS region [1]. This works more or less. Rather less for us-west [2]. For a simple failover this shouldn&#x27;t matter.<p>[1] AWS Regions: 
ap-northeast-1: Asia Pacific (Tokyo)
ap-southeast-1: Asia Pacific (Singapore)
ap-southeast-2: Asia Pacific (Sydney)
eu-central-1: EU (Frankfurt)
eu-west-1: EU (Ireland)
sa-east-1: South America (Sao Paulo)
us-east-1: US East (N. Virginia)
us-west-1: US West (N. California)
us-west-2: US West (Oregon)<p>[2] For me the most parts of the US are mapped to us-east, even most part of the west coast. However, I am a noob in regards to DNS routing realities.
