Amazon Athena is now available in AWS South America (São Paulo)

Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run. 

With the latest release, Amazon Athena is now available in US East (Northern Virginia, & Ohio), US West (Oregon, & N. California), AWS GovCloud, Europe (Ireland, Frankfurt, London, Stockholm, and Paris), Asia Pacific (Singapore, Tokyo, Sydney, Seoul, & Mumbai), and South America (São Paulo) regions.
