Instantly test if any website is offline, slow, or returning errors — for everyone or only you. HTTP status, SSL, TTFB, IP & bulk URL checks in one free tool.
Far more than a ping — a complete real-time diagnostic of any URL, server-side.
We send an actual server-side HTTP cURL request — what Google, bots, and visitors really see — not a browser ping from your own machine.
Validates HTTPS certificates in real-time. An expired SSL causes browser warnings even when the server itself is running fine.
Measures DNS lookup, TCP connection, and Time to First Byte separately — pinpoint exactly where latency comes from.
Follows up to 10 hops and reports the final effective URL — perfect for spotting redirect loops or chains that cost PageRank.
Reveals server software (Nginx, Apache, Cloudflare) and Content-Type — catch misconfigurations at a glance.
Test up to 50 URLs at once. Ideal for site audits, uptime monitoring after migrations, or checking entire project portfolios.
Download bulk results as CSV — ready for reporting, client handovers, or importing into monitoring dashboards.
Resolves domains to IP addresses instantly. Confirm DNS propagation, identify CDNs, or spot IP-level blocking.
Every HTTP response code gets a human-readable explanation — instantly understand what 502, 503, 429 or 410 means for your site.
No account. No extension. No install. Results in under 10 seconds.
Paste any website address. You can include or omit https:// — we handle both.
Our server fires a real cURL request directly to your URL, independent of your network.
See HTTP code, response time, SSL status, IP, server type, and page size in a clear card.
Down globally? Contact your host. Only you? Flush DNS, clear cache, or switch networks.
Staring at a blank screen or an error page is one of the most disorienting moments in modern browsing. You hit refresh, wait a few seconds, and nothing changes. The question surfaces almost immediately: is this website down for everyone, or is it just me? It sounds simple, but the answer determines whether you spend the next hour troubleshooting your own setup or simply wait for someone else to fix a problem on their end.
When a website is down for everyone, the root cause is always server-side. The web host might be experiencing an outage, the origin server could have crashed, the domain may have expired or lost its DNS records, or an unexpected traffic spike overwhelmed the infrastructure. No amount of refreshing, clearing browser cache, or restarting your router will fix a global outage — the fix has to happen at the server level. Knowing this early saves you from wasted troubleshooting time and lets you focus on what actually matters: reaching your host's support team.
On the other hand, if a webpage is down only for you, the problem is almost always local. Your ISP might be routing requests incorrectly, your DNS resolver might be caching a stale IP address, or your browser might be serving a broken cached version of the page. Regional firewall rules, VPN conflicts, and ISP-level DNS filtering can all make a perfectly healthy site appear completely unreachable on your device while everyone else loads it without issue.
Our website status checker cuts through the uncertainty entirely. Instead of relying on your own browser or internet connection, our tool sends an independent HTTP cURL request from our server to the URL you provide. If our server reaches the site and receives a successful response, the website is online — and your local network is the likely culprit. If our server also fails to connect, the site is down for everyone, and you can stop troubleshooting your connection immediately.
Beyond a simple up-or-down answer, a proper is it down checker should give you real diagnostic depth. The HTTP status code tells the full story: a 200 OK means everything is healthy; a 503 Service Unavailable suggests the server is alive but overwhelmed; a 502 Bad Gateway points to a problem between a proxy or CDN and the origin; and a complete connection failure means the domain itself is unreachable at the DNS or network layer. Armed with this information, both site owners and everyday visitors can make faster, smarter decisions — whether that means contacting hosting support, flushing local DNS cache with ipconfig /flushdns, switching to a public resolver like Cloudflare's 1.1.1.1, or simply closing the tab and checking back later once the outage resolves.
Enter the URL in our checker and click Check Status. Our server sends its own independent HTTP request from a neutral network. If we can reach it fine, the problem is local — try flushing DNS (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on macOS), clearing browser cache, or switching to Google's 8.8.8.8 or Cloudflare's 1.1.1.1. If our server also fails to connect, the site is confirmed down globally.
HTTP 5xx codes are the clearest server-side indicators: 500 (Internal Server Error), 502 (Bad Gateway — proxy can't reach origin), 503 (Service Unavailable — overloaded or maintenance), and 504 (Gateway Timeout). A complete connection failure or DNS error means the server or domain is entirely unreachable. HTTP 4xx codes (404, 403) usually mean the server is up but the specific page or access is restricted.
Yes — switch to the Bulk Check tab and paste up to 50 URLs, one per line. Hit Check All URLs and the tool tests each one in sequence, showing a colour-coded results table with HTTP code, response time, SSL, server info, and IP for every URL. When done, export the full results as a CSV file for offline reporting or client documentation.
