The Stream Chat API is hosted in 4 publicly available locations
When creating an App we advise that it is created in the region closest to where the majority of the users will be connecting from. We are unable to migrate existing applications from one region to another, so it's important to select the best region when you create an app.
The Stream SDKs will default to the US East location. If you are using the SDK in another region, change the URL of API calls by following these instructions.
