Down for everyone, or just me?

Our checker tests the site from our infrastructure, not your device. This means:

  • Our check passes, but you can’t load it — the issue is local to you or your network. Try another device, clear your cache, or switch from Wi-Fi to mobile data.
  • Our check fails, and you can’t load it — the site is likely down for everyone. Wait and check back in a few minutes.
  • Our check passes, and you can load it — no issue detected. If you were seeing a problem, it may have already resolved.

What we check

DNS Resolution

Verifies the domain resolves to an IP address. Fails if the domain doesn't exist or DNS is propagating.

HTTP Response

Sends a real HTTP request and records the status code and response time. Retries with GET if HEAD is blocked.

SSL / TLS

Checks whether HTTPS is working and estimates days until the certificate expires.

Latency

Measures round-trip response time in milliseconds. Over 3 seconds is flagged as slow.

Common causes of website errors

DNS propagation

New domains or recent DNS changes can take up to 48 hours to spread globally. During this time, some users may see the site while others cannot.

Expired or invalid SSL certificate

If the site's HTTPS certificate has expired, browsers block access even if the server is running. This is a server-side issue the site owner must fix.

Server timeout or overload

The web server may be overwhelmed with traffic, running out of memory, or experiencing a software crash.

Blocked by your ISP or region

Some websites are geo-restricted or blocked by certain internet providers. A VPN can help test whether this is the cause.

Local network issue

Your home router, firewall, or DNS resolver may be causing the problem. Try switching to mobile data to isolate this.

Browser cache or extension conflict

A cached error page or browser extension (e.g., ad blockers, VPN) may be interfering. Try in a fresh incognito window.

Privacy notice

We check the public URL you provide. Only the hostname (not full path or query string) is stored in our database to prevent caching sensitive URLs. Results are not associated with your identity. Do not check URLs that contain private data or authentication tokens.

Frequently asked questions

Is this website down for everyone or just me?

Our checker tests the site from our servers, not your device. If our check passes but you cannot load the site, the issue is local — try another browser, clear your cache, or switch networks. If our check fails, the site is likely down globally.

How accurate is the website down checker?

We test DNS resolution, HTTP response, and SSL certificate from our infrastructure. Results reflect the site's availability from our vantage point. Local network issues, geo-blocking, or CDN anomalies may cause different results for individual users.

Can I check any website, not just popular ones?

Yes. Enter any public domain or URL. We block internal/private IP ranges and local addresses for security. Do not enter URLs containing authentication tokens or sensitive data.

What does a DNS error mean?

A DNS error means the domain name could not be resolved to an IP address. This can happen if the domain does not exist, has expired, or if DNS changes are still propagating (which can take up to 48 hours).
