How does multi-region website checking work?

We send requests to your website from 9 different locations around the world simultaneously. This helps identify if your site is experiencing regional outages, CDN issues, or geo-blocking that might not be visible from a single location test.

What does "external resources" mean?

External resources are files your website loads from other servers — like Google Fonts, CDN-hosted JavaScript libraries, analytics scripts, or third-party APIs. If any of these fail to load, your website may appear broken to visitors even if your server is online.

Why is my site showing as "down" in some regions?

This could be due to: CDN misconfiguration, geo-blocking by your hosting provider, DNS propagation delays, regional server outages, or firewall rules blocking certain IP ranges. Our tool helps you identify exactly which regions are affected.

How often should I check my website availability?

For manual checks, we recommend testing after any infrastructure changes, DNS updates, or when users report issues. For continuous monitoring, our paid plans check your site every 1-5 minutes from multiple regions automatically.

Is this tool really free?
