To reduce latency and increase availability, store your data close to\nthe users and services that need it.\n\nYou can optionally create multiple buckets in your project, each with its own\nlocation setting. For details, see the Cloud Storage getting started guide for\nyour platform (\n[iOS+](/docs/storage/ios/start#use_multiple_storage_buckets) \\|\n[Android+](/docs/storage/android/start#use_multiple_storage_buckets) \\|\n[Web](/docs/storage/web/start#use_multiple_storage_buckets) \\|\n[Flutter](/docs/storage/flutter/start#use_multiple_storage_buckets) \\|\n[Unity](/docs/storage/unity/start#use_multiple_storage_buckets) \\|\n[C++](/docs/storage/cpp/start#use_multiple_storage_buckets)\n).\n\nBe aware that once you provision a bucket, you cannot change its location\nsetting.\n\nIn the Google Cloud Storage documentation, you can find more information\nabout location settings and\n[available Cloud Storage locations](https://cloud.google.com/storage/docs/locations#available-locations).\nThese locations are applicable to your default Cloud Storage bucket with the name\nformat \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.firebasestorage.app` as well any additional\nCloud Storage buckets in your project.\n| **Note:** At this time, Cloud Storage for Firebase does not support [configurable dual-regions](https://cloud.google.com/storage/docs/locations#configurable).\n\nBuckets in `US-CENTRAL1`, `US-EAST1`, and `US-WEST1` can take advantage of the\n[\"Always Free\" tier](https://cloud.google.com/storage/pricing#cloud-storage-always-free) for Google Cloud Storage. Buckets\nin all other locations follow\n[Google Cloud Storage pricing and usage](https://cloud.google.com/storage/pricing).\n| **Important** : If your project has a default Cloud Storage bucket with the name format \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.appspot.com`, note the following about its location:\n|\n| - Its location is one of the [available Google App Engine locations](https://cloud.google.com/about/locations#region).\n| - Its location has a dependency on the [\"location for default Google Cloud resources\"](/docs/projects/locations#default-cloud-location). When you provisioned that default bucket, the location might have already been set, either during project creation or when setting up another service that shares this location dependency.\n|\n| The location setting for a default Cloud Storage bucket with the name\n| format \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.firebasestorage.app` does not share this\n| dependency."]]
