Vercel Sandbox domains resolve 18x faster globally

Vercel has upgraded the routing architecture for Vercel Sandbox public domains, shifting domain resolution from a single centralized store to regional replicas across all 19 compute regions. This update cuts global median lookup latency from 62ms down to 3.4ms (an 18x speedup) and applies automatically with no configuration or pricing changes.

// ANALYSIS

Distributing routing state to regional replicas transforms ephemeral sandbox environments from sluggish prototypes into responsive production-ready runtime infrastructure. Eliminating centralized bottleneck penalties slashes global median lookup latency by 18x and delivers dramatic p99 gains in remote regions. Delivering this out-of-the-box performance boost without code refactoring or price hikes directly benefits latency-sensitive AI agent loops and interactive previews that rely on microVM execution.
