# Multi-region Support

Stream's Chat infrastructure is partially replicated on several regions, allowing developers all around the globe to optimize for network latency by mapping their usage to the region closest to their users. There is support for Chat in US East, EU West, Singapore, Sydney and Mumbai.

Users can now arbitrarily create apps in the location of their choice, without any action or approval needed from our side. Two steps are required to do so :

### Dashboard Server Location

For Chat, users will first choose hosting their app in our US East, EU West, Singapore, Sydney or Mumbai server instances.

Once you've set the region for your application, it cannot be changed.

### Client Location Settings

Stream's new [Edge infrastructure](https://getstream.io/blog/chat-edge-infrastructure/) removes the need to specifically set a regional URL. The baseURL is `https://chat.stream-io-api.com` regardless of region.
