Block Checker

Welcome to the ZeoTools Block Checker, a bulk domain block test that takes one template URL and replays it across every domain you list. Paste the address your visitors actually land on, add the other domains, and each one is requested with the same path and query string still attached. It runs alongside the rest of our free toolkit, including the Web Inspector, with no registration and no daily quota.

Why the query string matters: Many landing pages behave differently depending on their parameters, so checking a bare domain tells you very little. This mirror checker keeps /?register&ref=abc&utm_source=google exactly as typed, character for character, and only swaps the hostname. Values are never re-encoded or reordered, so a valueless flag survives intact. Type a domain without a scheme and https:// is added for you.

How a block is detected: Each response is read in full, not just its status code. A Cloudflare firewall page, an ISP or TrustPositif interstitial, HTTP 451, and a plain 403 are all reported as blocked, while DNS failures, refused connections, and timeouts are separated out as unreachable so you can tell censorship apart from a dead server. Use our Nawala Checker when you specifically need the Indonesian TrustPositif verdict.

One honest limitation: Requests leave from our datacenter, not from your home connection. A firewall that blocks server IP ranges will show as blocked here even when a normal visitor gets through, and a nationwide DNS block may not appear at all. Treat the result as one vantage point among several, and confirm anything critical from the network you actually care about.
