Maybe I missed this in the link but I didn't see how one of the common problems in a distributed application is addressed:

* A POST request is redirected to the primary data source, the resource is created and the id is returned

* A GET request is immediately issued for that id but the resource that has not been replicated to the regional data source

* :boom:

Our Rails gem pins requests to the primary region until the data is replicated.

We talk about this more here: https://fly.io/blog/globally-distributed-postgres/
