About the website status tools
These tools answer the questions people ask when a site misbehaves. Is it down? What is the server sending back? Where does this link really end up? Why does the page take so long to start loading? Every check runs from our server, in one location, so you see how the site responds from there rather than through your own connection, browser cache or network.
They suit site owners checking a launch or a move to a new host, developers chasing a broken redirect, support teams answering “is it just me?”, and anyone who can’t get a page to open.
Which tool to use
If a site won’t load, start with the Website Down Checker. It walks through DNS, the connection, the certificate and the HTTP response, then gives you a verdict and a link you can share. For a broader look at one address, the Website Health Report adds security headers and the domain’s mail and DNS records on a single page.
The remaining tools each focus on one part. The HTTP Status Checker shows the status code and headers a URL returns. The Redirect Checker follows a chain of up to five hops and flags loops and downgrades from HTTPS. The Response Time Test splits three requests into DNS, connection, TLS and first-byte time. The Ping Test measures latency over five TCP connections, because ordinary pings are often blocked. The Bulk URL Checker runs the down checker’s test on up to 20 addresses at once.
