Can I select storage region or self-host Sanity storage?

Great questions about Sanity's data storage! Let me address both of your concerns:

1. Where is the storage located? Can I select a specific region?

According to Sanity's Terms of Service, Sanity uses Google Compute Engine servers and Google Container Engine clusters at data centers in St. Ghislain, Belgium as the primary location for storing your content data.

Currently, you cannot select a specific region like East Europe for your data storage. All content is stored in Belgium (as the primary location), though query data is distributed worldwide across Sanity's CDN network for optimal performance.

However, according to the community discussion, the ability to select your origin region is something Sanity plans to offer in the future. This is a common request, especially for organizations with specific data residency requirements.

For the most up-to-date information about data residency options, I'd recommend contacting Sanity's sales team directly, especially if you have specific compliance requirements for your work projects.

2. Can I install the storage on one of my servers?

No, Sanity is a fully hosted service - there is no way to self-host the data store on your own servers. Sanity operates as a cloud-based platform where the Content Lake (Sanity's content database) is managed entirely by Sanity.

This is by design - Sanity handles all the infrastructure, scaling, security, and maintenance so you can focus on building your applications rather than managing databases and servers.

What you CAN do:

• Host your frontend applications (built with Next.js, React, etc.) wherever you want
• Run Sanity Studio (the content editing interface) on your own infrastructure
• Use Sanity Functions for serverless compute within Sanity's infrastructure
• Export your content via APIs if needed for other purposes

The architecture is designed so that your content lives in Sanity's Content Lake, but you have complete control over how you query, transform, and present that content in your applications.

If self-hosting is a hard requirement for your organization, you might need to explore other solutions, but I'd still recommend discussing your specific needs with Sanity's team - they may have enterprise options or upcoming features that could work for you.
