Vercel Sandbox Expands Globally
💡Reduce Sandbox latency and add regional failover for AI development workloads.
⚡ 30-Second TL;DR
What Changed
Sandboxes now run in Washington, D.C., San Francisco, Cleveland, and Paris.
Why It Matters
Global region selection can improve responsiveness for AI development workflows that access remote databases, object storage, or inference services. Failover support also improves resilience for production-grade sandbox automation.
What To Do Next
Update your Vercel Sandbox SDK or CLI, then set a region near your data services and a failover region in Vercel project settings.
Key Points
- •Sandboxes now run in Washington, D.C., San Francisco, Cleveland, and Paris.
- •Teams can select a region near their databases and object storage to reduce latency.
- •Pro and Enterprise teams can configure failover regions for new sandboxes.
- •Region defaults can be managed in project settings or overridden through the SDK and CLI.
