Is This Website Down?
Enter the website address for an independent server-side check. See whether it responds, the HTTP status and response time, plus DNS and SSL evidence that can explain why it is not loading for you.
One independent server location—not a worldwide outage map. A firewall or bot rule can block the check even while the site remains available to visitors.
Do not wait for someone to ask if the site is down.
Monitor one site free forever. SitesRadar checks automatically and emails you when it starts failing, alongside SSL, DNS, broken-link and other health alerts.
How to read the result
Reachable
The site answered our server. If it still fails for you, try another network or device and clear local DNS and browser caches. The problem is more likely local or regional.
Unreachable
The connection did not complete. The report helps separate DNS, TLS and timeout failures. Confirm from another network before calling it a worldwide outage.
Blocked or partial
The site responded but limited inspection. A CDN or web application firewall may allow browsers while rejecting automated requests. SitesRadar labels that uncertainty instead of guessing.
Down for everyone or just me?
- 01
Get an independent result
Run the check above so your browser, cache and current network are not the only evidence.
- 02
Compare another network
Try phone data if you are on Wi-Fi. If only one network fails, investigate its DNS, VPN or firewall.
- 03
Use the failure evidence
DNS errors, certificate failures, redirects and HTTP status codes point to different fixes. The full report keeps them together.
What the website status check includes
Reachability, HTTP status and response time
See whether the connection completed, how the server answered and how long the response took.
DNS resolution
Confirm that the domain resolves before spending time debugging the application server.
SSL certificate and HTTPS
Catch an expired or invalid certificate and see whether plain HTTP redirects safely to HTTPS.
A broader website health sweep
The same run also checks redirects, broken links, domain expiry and homepage metadata when the site can be inspected.

Diagnose what failed
Stop finding out at 11pm
What to look for when a site goes down is your client's problem, not yours.

Client-site downtime triage
Work through DNS, SSL, hosting, application and CDN failures in order.
Check the SSL certificate
Inspect validity, certificate chain and the exact expiry date.
Investigate DNS changes
Understand how silent record changes turn into apparent outages.
"This site can't be reached"
Read the browser's error code to tell DNS, firewall and server failures apart.
ERR_CONNECTION_REFUSED
The server was reached and said no — usually a stopped web server or firewall.
Expired domain
Why a lapsed registration looks like an outage, and how to recover it.
Frequently asked questions
- How do I check if a website is down?
- Enter the website address above and run the free check. SitesRadar connects from an independent server and reports reachability, HTTP status, response time, DNS and SSL evidence.
- Is the website down for everyone or just me?
- If our server reaches it but your browser cannot, the problem is likely local to your device or network. If both fail, the site may be down, though DNS, TLS, firewall rules or bot protection can also block the automated connection.
- Why does a website work for me but not someone else?
- A stale DNS cache, VPN, corporate firewall, browser extension, CDN region or cached page can affect one visitor and not another. Compare another network with the independent result above.
- Does unreachable always mean the server is offline?
- No. DNS, TLS, timeouts, CDN rules and web application firewalls can all prevent a check from completing. SitesRadar reports the evidence it collected instead of labeling every failure a confirmed global outage.
- Does SitesRadar check from multiple locations?
- This free checker uses one independent server location, not a worldwide probe network. When regional availability matters, compare it with another device or network.
- Can SitesRadar monitor the website after this check?
- Yes. The free plan monitors one site automatically and emails you when checks start failing. It also watches SSL expiry, broken links, DNS and other website-health signals.
