Website Down Checker
Free, no signup. Is it down from this independent Cloudflare vantage point? Check one URL for its current response, redirect path, and a bounded explanation.
Checks run from our server; we fetch the URL you enter and don't keep the results. This is one point-in-time request from a Cloudflare location, not a multi-region uptime monitor. HTTPS results show only whether a connection completed — never certificate expiry or full TLS details. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.
Sample report
Illustrative example — deterministic fixed response data
Reachable, but returning an error
The server responded with HTTP 503; that is different from a network outage.
842 ms · TLS handshake succeeded.
- 301 — http://example.test/status
- 503 — https://example.test/status
The example is classified from the shown status, hops, latency, and TLS state. It does not claim that example.test was requested.
How to use it
- Enter the exact page URL, including HTTPS and path when relevant.
- Choose Check website and read the reachability verdict before the timing.
- Inspect the redirect chain to confirm the final response is the page you expected.
- Follow the DNS, hosting, and RDAP links when the report receives no HTTP response.

What the results mean
- Reachable means the final status is below 400 from this location.
- Reachable, but returning an error means an HTTP 4xx or 5xx response arrived; the network path worked.
- DNS name not found is used when the fallback DNS probe returns NXDOMAIN.
- TLS connection failed, timed out, or not reachable describe the bounded failure evidence; they do not identify a certificate or origin root cause.
How it works
A Cloudflare Worker makes a bounded external request, records the redirect hops, final status, elapsed time, and whether an HTTPS connection completed. When no HTTP status arrives, a fallback DNS result and the returned error text help distinguish NXDOMAIN, TLS failure, timeout, and other unreachable states.
Features
- One point-in-time external reachability check.
- Final status plus complete observed redirect path.
- Latency and limited TLS-handshake state.
- DNS fallback evidence and prefilled diagnostic handoffs.
Limitations
This is not continuous or multi-region monitoring. It cannot prove availability for every user, inspect application correctness behind a 200, expose certificate details, bypass bot protection, or distinguish every firewall, routing, DNS, origin, and transient network cause.
Frequently asked questions
Is the website down for everyone or just me?
This checker can only say what happened from one Cloudflare location at one moment. Compare another network or a multi-region monitor before concluding that everyone is affected.
Does an HTTP 500 mean the website is down?
The server is reachable, but it is returning an application or server error. The tool labels that “reachable, but returning an error” rather than treating it as a network outage.
Can the checker diagnose an expired TLS certificate?
No. It reports whether a secure connection completed or failed, but the Worker interface does not expose certificate expiry, chain, hostname, or cipher details.
Why does the site work for me but show as unreachable here?
The target may vary by geography, IP reputation, firewall policy, DNS resolver, user-agent, cache, or timing. A single external vantage point is useful evidence, not an uptime consensus.

حول الأداة
تحقّق ما إذا واحد عنوان URL هو قابل للوصول من واحد Cloudflare موضع الصحيح الآن, مع حالة, سلسلة إعادة التوجيه, توقيت, DNS بديل احتياطي دليل, و صادق TLS حدود.
مجاني, من دون تسجيل. هو إنه down من هذا مستقل Cloudflare منظور نقطة? تحقّق واحد عنوان URL من أجل الخاص به حالي استجابة, إعادة التوجيه مسار, و واحد محدود شرح.
الميزات
- واحد في لحظة محددة خارجي reachability تحقّق.
- نهائي حالة بالإضافة مكتمل مرصود إعادة التوجيه مسار.
- زمن الاستجابة و محدود TLS-handshake حالة.
- DNS بديل احتياطي دليل و prefilled تشخيصي عمليات تسليم.
كيفية العمل
واحد Cloudflare Worker يجعل واحد محدود خارجي طلب, سجلات ال إعادة التوجيه قفزات, نهائي حالة, elapsed وقت, و ما إذا واحد HTTPS اتصال مكتمل. عندما لا HTTP حالة يصل, واحد بديل احتياطي DNS نتيجة و ال مُعاد خطأ نص help distinguish NXDOMAIN, TLS فشل, مهلة, و آخر غير قابل للوصول حالات.
القيود
- هذا هو ليس continuous أو multi-region مراقبة. إنه لا يمكن يثبت availability من أجل كل مستخدم, افحص تطبيق correctness خلف واحد 200, يكشف certificate تفاصيل, bypass bot حماية, أو distinguish كل جدار حماية, routing, DNS, الأصل, و transient شبكة سبب.
الأسئلة الشائعة
هو ال موقع ويب down من أجل everyone أو فقط me?
هذا فاحص يمكن فقط يقول ما حدث من واحد Cloudflare موضع في واحد moment. قارن آخر شبكة أو واحد multi-region مراقبة قبل concluding ذلك everyone هو متأثر.
يفعل واحد HTTP 500 يعني ال موقع ويب هو down?
ال خادم هو قابل للوصول, لكن إنه هو returning واحد تطبيق أو خادم خطأ. ال الأداة تسميات ذلك “قابل للوصول, لكن returning واحد خطأ” بدلًا من معالجة إنه باعتباره واحد شبكة انقطاع.
يمكن ال فاحص شخّص واحد expired TLS certificate?
لا. إنه يبلّغ ما إذا واحد آمن اتصال مكتمل أو فشل, لكن ال Worker واجهة يفعل ليس يكشف certificate expiry, سلسلة, hostname, أو cipher تفاصيل.
لماذا يفعل ال موقع عمل من أجل me لكن اعرض باعتباره غير قابل للوصول هنا?
ال هدف قد يختلف بواسطة geography, IP سمعة, جدار حماية سياسة, DNS resolver, user-agent, ذاكرة مؤقتة, أو توقيت. واحد مفرد خارجي منظور نقطة هو مفيد دليل, ليس واحد uptime consensus.
