What this tool checks

  • HTTP status and response time per location
  • Connection and DNS errors per location
  • Whether the problem is regional or global

How to read the result

Each row is one probe location. If all locations fail, the site is down for everyone. If only some fail, the cause is regional: a CDN edge, a routing problem or a geo-block. Locations come from the probe servers configured for this site.

Frequently asked questions

Which locations are checked?

The primary server plus every probe the site operator has connected. The table shows exactly which ones responded.

Why would a site fail only in one region?

Typical causes are a CDN edge problem, a regional ISP routing fault, DNS differences or a firewall rule that blocks some countries.

Can I add more locations?

Yes. Site operators can run this application on additional servers and list them as probes. The README explains the setup.
