To reduce latency and increase availability, store\nyour data close to the users and services that need it.\n\nYou can optionally [create multiple databases](/docs/firestore/manage-databases) in your\nproject, each with its own location setting.\n\nBe aware that once you provision a database, you cannot change its\nlocation setting.\n\nTypes of locations\n\nYou can store your Cloud Firestore with MongoDB compatibility data in a\n[*multi-region* location](#location-mr) or a [*regional* location](#location-r).\n\nMulti-region locations\n\nSelect a multi-region location to maximize the availability and\ndurability of your database.\n\nA multi-region location consists of a defined set of\n[regions](https://cloud.google.com/docs/geography-and-regions#regions_and_zones) where multiple replicas of the database\nare stored. Each replica is either a read-write replica which contains all of the\ndata in the database or a witness replica which does not maintain a full set of\ndata but participates in replication.\n\nBy replicating the data between multiple regions, data\ncan continue to be served even with the loss of an entire\nregion. Within a region, data is replicated across\n[zones](https://cloud.google.com/docs/geography-and-regions#regions_and_zones) so that data can continue to be served\nwithin that region even with the loss of a zone.\n\nCloud Firestore with MongoDB compatibility supports the following multi-region locations:\n\n| Multi-region name | Multi-region description | Read-Write regions | Witness region |\n|-------------------|----------------------------------|------------------------------------------------------------------------------|--------------------------------------------------------|\n| `eur3` | Europe | `europe-west1` (Belgium), `europe-west4` (Netherlands) | `europe-north1` (Finland) |\n| `nam5` | United States (Central) | `us-central1` (Iowa), `us-central2` (Oklahoma---private Google Cloud region) | `us-east1` (South Carolina) |\n| `nam7` | United States (Central and East) | `us-central1` (Iowa), `us-east4` (Northern Virginia) | `us-central2` (Oklahoma---private Google Cloud region) |\n\nRegional locations\n\nA regional location is a specific geographic place, such as South Carolina. Data\nin a regional location is replicated in multiple zones within a\n[region](https://cloud.google.com/docs/geography-and-regions#regional_resources). All regional locations are separated from other regional\nlocations by at least 100 miles.\n\nSelect a regional location for lower costs, for lower write latency if your\napplication is sensitive to latency, or for\n[co-location with other Google Cloud resources](https://cloud.google.com/about/locations/#products-available-by-region).\n\nCloud Firestore with MongoDB compatibility supports the following regional resource locations:\n\n| | Region name | Region description |\n|---|---------------------------|--------------------|\n| **North America** |||\n| | `us-west1` | Oregon |\n| | `us-west2` | Los Angeles |\n| | `us-west3` | Salt Lake City |\n| | `us-west4` | Las Vegas |\n| | `us-central1` | Iowa |\n| | `northamerica-northeast1` | Montréal |\n| | `northamerica-northeast2` | Toronto |\n| | `northamerica-south1` | Queretaro |\n| | `us-east1` | South Carolina |\n| | `us-east4` | Northern Virginia |\n| | `us-east5` | Columbus |\n| | `us-south1` | Dallas |\n| **South America** |||\n| | `southamerica-west1` | Santiago |\n| | `southamerica-east1` | São Paulo |\n| **Europe** |||\n| | `europe-west2` | London |\n| | `europe-west1` | Belgium |\n| | `europe-west4` | Netherlands |\n| | `europe-west8` | Milan |\n| | `europe-southwest1` | Madrid |\n| | `europe-west9` | Paris |\n| | `europe-west12` | Turin |\n| | `europe-west10` | Berlin |\n| | `europe-west3` | Frankfurt |\n| | `europe-north1` | Finland |\n| | `europe-north2` | Stockholm |\n| | `europe-central2` | Warsaw |\n| | `europe-west6` | Zürich |\n| **Middle East** |||\n| | `me-central1` | Doha |\n| | `me-central2` | Dammam |\n| | `me-west1` | Tel Aviv |\n| **Asia** |||\n| | `asia-south1` | Mumbai |\n| | `asia-south2` | Delhi |\n| | `asia-southeast1` | Singapore |\n| | `asia-southeast2` | Jakarta |\n| | `asia-east2` | Hong Kong |\n| | `asia-east1` | Taiwan |\n| | `asia-northeast1` | Tokyo |\n| | `asia-northeast2` | Osaka |\n| | `asia-northeast3` | Seoul |\n| **Australia** |||\n| | `australia-southeast1` | Sydney |\n| | `australia-southeast2` | Melbourne |\n| **Africa** |||\n| | `africa-south1` | Johannesburg |\n\nLocation SLA\n\nYour Cloud Firestore with MongoDB compatibility location type determines the\n[Service Level Agreement (SLA)](/terms)\nuptime percentage at General Availability (GA):\n\n| Covered service | Monthly uptime percentage |\n|---------------------------------------------------------|---------------------------|\n| Cloud Firestore with MongoDB compatibility Multi-Region | \\\u003e= 99.999% |\n| Cloud Firestore with MongoDB compatibility Regional | \\\u003e= 99.99% |\n\nLocation pricing\n\nYour Cloud Firestore with MongoDB compatibility location determines the cost of database\noperations.\n\nFor a comprehensive explanation of pricing per region and per region type,\nsee [Understand Cloud Firestore with MongoDB compatibility billing](https://firebase.google.com/pricing).\n\nView the location of your databases\n\nUse one of the following methods to view the location setting for your databases:\n\n- Run the [`gcloud firestore databases list`](https://cloud.google.com//sdk/gcloud/reference/firestore/databases/list)\n command.\n\n- Open the\n [database list](https://console.cloud.google.com/firestore/databases) in the Google Cloud console.\n The location for each database is in the location column.\n\nNext steps\n\n- To create a Cloud Firestore with MongoDB compatibility database in a specific location, see\n [Create and manage databases](/docs/firestore/manage-databases)\n\n- For more information about building applications to meet your latency,\n availability, and durability requirements, refer to\n [Geography and Regions](https://cloud.google.com/docs/geography-and-regions#multi-regional_resources)."]]
