Hello @ukaszBoru
There is a hacky way of doing it, as described in this thread on the topic.
Once you extract the <meta name="ajs-region" content="..."> from the HTML response, the content attribute will contain a code that correlates to the AWS region that is hosting the instance.
Here is a list of AWS region codes from Amazon. You’ll have to manually work out what region relates to which code, as this list also contains the extra zone info, and there can be multiple zones for a region.
Remember, this is location of the compute part of the system and might not be where the data is residing.
