All free tools Checked from VPSLake

Website Down Checker

Is the website down for everyone or just you? Test its HTTP status, load time and latency, see whether Cloudflare or another firewall is blocking the request, and view a live screenshot of what the site actually returned.

WEBSITE AVAILABILITY

Check a website

Live test
Enter a public HTTP or HTTPS website. If you omit the protocol, the checker uses HTTPS.

Your check is processed on the VPSLake server. The URL is used only for this live test and screenshot; it is not saved by the tool. Private and internal network addresses are blocked.

HOW TO USE IT

Check a site in four steps

No account or browser extension is needed for this website status checker. One address is all it asks for.

  1. 1

    Enter the website address

    Paste a public domain or full page URL, such as https://example.com/status.

  2. 2

    Run the live check

    Select Check Website Status. Our server makes a limited cURL request and safely follows public redirects.

  3. 3

    Read the status, load time, and latency

    See whether the server answered, the final HTTP status code, the total load time, and how many milliseconds went into DNS, connection, TLS, server response, and download.

  4. 4

    Check the firewall verdict and screenshot

    If Cloudflare or another firewall answered instead of the site, the result says so rather than calling the site down. The screenshot shows exactly what came back, including a block or challenge page.

Is the website down?

This website down checker contacts the URL from a VPSLake server rather than relying on your current browser connection. If the server receives an HTTP response, the result shows its status code and how long the cURL request took.

A successful 2xx or 3xx response normally means the page is online. A 4xx or 5xx response proves the web server answered, but the requested page or application returned an error that may still need attention.

Is it down for everyone or just me?

If a site opens here but not on your device, the issue may be local DNS, a browser cache, a firewall, your internet provider, or a regional restriction. If this site down checker also cannot connect, the website may be unavailable more broadly.

No single check can prove worldwide availability. Monitoring from several locations over time is better for diagnosing intermittent or regional outages.

Blocked by a firewall is not the same as down

Most simple checkers report any refused request as an outage. This one reads the response headers, cookies, and page body to name the layer in front of the site, such as Cloudflare, Sucuri, Imperva, Akamai, AWS WAF, Wordfence, ModSecurity, or F5 BIG-IP.

When that layer answers with a bot challenge, a 403 block page, or an HTTP 429 rate limit, the result says the site is blocked, not down. Sites often treat requests from data centre addresses this way while serving normal visitors perfectly well.

What the load time and latency mean

The total load time is how long the whole request took from our server. The breakdown splits it into the DNS lookup, the TCP connection, the TLS handshake, the server's own thinking time before the first byte, and the download of the response.

Network latency is the connection time: it shows how far away the server is. A low connect time with a high server response usually points at slow application or database code rather than the network.

What this availability check does not measure

The reported times are server-side request timings, not a complete Core Web Vitals or browser performance test. The screenshot blocks third-party origins for safety, so externally hosted fonts, scripts, images, or styles may be absent even when the website itself is working. Firewall detection reads the signatures a protection layer exposes in its response; a silent filter that simply drops packets appears as a connection timeout instead, and a private or custom firewall may not be named at all.

FREQUENTLY ASKED QUESTIONS

Website Down Checker FAQ

The VPSLake server resolves the public domain, makes a time-limited cURL request, safely follows up to five public redirects, and reports the final HTTP status with a millisecond breakdown of DNS, connection, TLS, server response, and download. It then inspects the response headers, cookies, and page body to identify any CDN or web application firewall and decide whether that layer blocked the request. A restricted browser process finally attempts an in-memory screenshot of responding HTML pages.
This tool checks from one VPSLake server. A successful result while the site fails for you suggests a local or regional issue, but one test cannot represent every network worldwide.
Not always. A 404 means the server responded but could not find that particular URL. A 500-series response means the server or application returned an error. Other pages on the same domain may still work.
The screenshot uses a clean 1280 × 720 browser session and allows resources only from the final checked origin. Cookie-based content, login states, location-dependent pages, and assets hosted on third-party domains can therefore look different or be missing.
Total load time is the whole server-side request, including every redirect and the receipt of the limited response body. Network latency is the connect stage on its own, which reflects the round-trip distance to the server. The breakdown chart separates DNS lookup, connection, TLS handshake, server response time before the first byte, and download. None of these is a visitor's full visual page-load time in a browser.
The tool does not save the entered URL or screenshot. The URL is processed on the VPSLake server for the live request, and the screenshot is returned from memory to your browser. Normal web-server security logs may record access to the checker endpoint, but the checked URL is sent in the request body rather than its address.
This is a public website availability checker, not a private network scanner. Localhost, private, reserved, special-use, authenticated, and non-standard-port URLs are rejected to protect internal systems.
It means a security layer answered the request instead of the website. Cloudflare and similar services often serve a bot challenge, a 403 block page, or an HTTP 429 rate limit to requests from data centre addresses. The site is reachable and almost certainly working for normal visitors, so treating it as an outage would be wrong. The screenshot shows the block or challenge page that was returned.
It recognises Cloudflare, Sucuri, Imperva Incapsula, Akamai, Amazon CloudFront, AWS WAF, Azure Front Door, Fastly, StackPath, Bunny CDN, DDoS-Guard, Qrator, Fortinet FortiWeb, Barracuda, F5 BIG-IP, ModSecurity, and Wordfence from their response headers, cookies, and block pages. A firewall that drops packets silently, or one with no public signature, will show as a connection timeout or as no protection detected.
Status codes from 520 to 527 come from Cloudflare itself, not from your site. They mean Cloudflare is healthy but could not get a usable response from your origin server: 521 is an origin that is down or refusing connections, 522 is a connection timeout, 523 is an unreachable origin, and 525 or 526 are TLS problems between Cloudflare and the origin. The checker reports these as an origin outage and names the likely cause, which is usually where you should start looking.
A few checks per minute per visitor, and only a small number run at once across the whole tool. Each check makes a single browser capture and closes it immediately, so the tool stays light and does not turn into a load generator against the sites it tests. If you see a busy message, wait a few seconds and try again.
