# Data residency

When you sign up with Reflag you automatically use our global infrastructure to guarantee low latency from your users' clients to our servers.

However, if you need your users' data to stay inside the EU you can contact us at <hello@reflag.com> and request we change your data residency to EU only.

By default, our SDKs connect to `front.reflag.com`. This points to our globally distributed edge servers and requests to this domain will be served generally by a server closest to the user.

However, if you're using the EU data residency, you must change the `apiBaseUrl` to `front-eu.reflag.com` when configuring the SDK to ensure the requests always land on one of our EU servers.

Here's how you can set the host in our Browser SDK and Node SDK:

```ts
// Browser SDK + Node SDK
const reflagClient = new ReflagClient({
    publishableKey: "{YOUR_PUBLISHABLE_KEY}",
    apiBaseUrl: "https://front-eu.reflag.com",
    ...
});
```

And using the React SDK:

```tsx
// React SDK
import { ReflagProvider } from "@reflag/react-sdk";

<ReflagProvider
  publishableKey="{YOUR_PUBLISHABLE_KEY}"
  company={{ id: "acme_inc" }}
  user={{ id: "john doe" }}
  apiBaseUrl="https://front-eu.reflag.com"
>
 ...
</ReflagProvider>
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.reflag.com/product-handbook/data-residency.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
