Core Web Vitals are a Google ranking factor. Sites with better vitals rank higher and get more organic traffic. Perfect scores mean more visibility for your business.

Visitors, Everywhere

Your site is served from the nearest edge location to each visitor. Someone in Tokyo gets your site from Tokyo. Someone in London gets it from London. Zero round trips to a distant origin server.

Sub-50ms Globally

Pages are pre-built and served from the edge, so there is no distant origin to wait on.

Automatic Routing

Traffic is intelligently routed to the fastest available edge.

Always Available

The network routes around trouble, so a bad day somewhere stays somewhere else.
