I feel silly asking this, but https://aws.amazon.com/blogs/aws/now-available-amazon-aurora... says "four regions" -- when I go to look at the Aurora price page (https://aws.amazon.com/rds/aurora/pricing/), it lists what looks like more than four.

Which is correct?

What I really want to know is whether I can use this in ap-northeast-1. :)

https://aws.amazon.com/about-aws/whats-new/2017/10/announcin... shows the four regions we are currently available in.

On https://aws.amazon.com/rds/aurora/pricing/, if you go to the "PostgreSQL Compatible" dropdown, you will see those same four regions.

We're working on making that page easier to parse, and the fact that you just ran into this confusion reinforces our committment to fix it - thank you!

Thank you for the understanding response!

I would like to add my vote for looking forward to support in ap-northeast-1 as well, then. :)
