Multi-Region ISR — Global Deployments with Consistent Cache States

In this tutorial, you will learn about Multi. We cover key concepts, practical examples, and best practices to help you master this topic.

When deploying ISR across multiple regions, each region's edge cache is independent. Coordinating revalidation ensures consistent content everywhere.

// Use webhooks to trigger revalidation in all regions
async function revalidateGlobally(path) {
  const regions = ['us-east', 'eu-west', 'ap-southeast'];
  await Promise.all(regions.map(region => 
    fetch(`https://${region}.api.com/revalidate?path=${path}`)
  ));
}
