SwiftNetScanWebsite Status Checker
Test whether a site answers from your own connection and how long it takes to respond.
Browsers restrict cross-origin responses, so some healthy sites that block external requests can report as unreachable. Treat this as a reachability signal, not an authoritative status code.
If a site won't load
- Try the same address on mobile data — that separates your network from the site.
- Switch DNS resolvers; a stale or blocked record is a common cause.
- Disable VPN or proxy software and retry.
- Clear the browser cache and test in a private window.
- Run a packet loss test to rule out an unstable path.
