I'm a developer in Australia and and I'm using the Firebase Realtime database for a project on Android and iOS.
Customers are complaining about lag and delays, especially when logging-in, and I'm trying to find out if any Firebase processes are by default on US servers, but can be moved to Asia to improve performance.
When I check my Google Cloud Console, the default Storage Bucket is set up as the US, but I cannot find any information about the Firebase Realtime Database.
When you open the RTDB console you can see it at the bottom as indicated in the image. This feature is currently in a beta state. https://firebase.google.com/docs/projects/locations?authuser=0#rtdb-locations
