vercel-sandbox regions failover latency infrastructure

Vercel Sandbox expands to four global regions

Sandbox now runs in iad1, sfo1, cle1, and cdg1; configure region and failover via CLI or SDK to minimize latency against your backend services.

Summary

Latency-sensitive workloads can now run closer to their databases and object storage, reducing round-trip times. Pro and Enterprise teams gain automatic failover, eliminating manual region failovers during outages.

Why it matters

Implementation verdict

Requires SDK/CLI update; replaces manual region workarounds. Region selection is plan-agnostic, failover is Pro/Enterprise only. Ready now—configure defaults in Settings or via `vercel project update`.
