App Engine is regional, which means the infrastructure that runs your apps is located in a specific region and is managed by Google to be redundantly available across all the zones within that region.
Meeting your latency, availability, or durability requirements are primary factors for selecting the region where your apps are run. You can generally select the region nearest to your app's users but you should consider the location of the other Cloud Platform products and services that are used by your app. Using services across multiple locations can affect your app's latency as well as pricing.
App Engine is available in the following regions:
- southamerica-east1 *
* For customers using the São Paulo region, all regional product SLAs will remain in force. However, multi-region and cross-region functionality spanning North America and South America may temporarily have reduced availability or performance.
You cannot change an app's region after you set it.
For information about selecting a region to create an App Engine application, see the Managing Projects, Applications, and Billing topic for your language in either the standard environment or flexible environment.
