criticalhit.com.au was checked by WebsiteStatus on October 19, 2026 at 9:40 PM. The server responded with HTTP status code 403 and a response time of 756 ms. The current status is: Client error. You can re-check this site at any time by clicking the "Re-check now" button above, or check another website from the home page.
Yes, you can check any subdomain. Just type the full address including the subdomain (for example, blog.example.com). WebsiteStatus will resolve the DNS and check whether that specific subdomain is up and responding. Each subdomain gets its own results page.
WebsiteStatus measures the total round-trip time of the HTTP request, including DNS resolution, connection setup, TLS handshake, and data transfer. The measurement reflects what a real visitor would experience. Note that response times can vary based on server load, network conditions, and geographic distance between our server and the target.
Status codes in the 200-299 range indicate success. 200 OK is the most common and means the page loaded normally. 201 means a resource was created (common in API responses). 204 means the server processed the request but returned no content. WebsiteStatus reports any 2xx or 3xx code as "Up & running."
WebsiteStatus checks whether the server is responding, but it does not scan for malware or content changes. However, the page title detection feature can give you a clue — if the title suddenly changes to something unexpected, it may indicate a defacement. For full security scanning, use a dedicated malware detection tool.
DNS (Domain Name System) translates a human-readable domain name like example.com into a machine-readable IP address. If DNS resolution fails, your website will be unreachable even if the server itself is running perfectly. WebsiteStatus verifies DNS records as part of the check process to help you rule out DNS issues.
The HTTP status code tells you how the server responded. 200 means the page loaded successfully. 301 or 302 means the page redirected to a new URL. 404 means the page was not found. 500 indicates a server-side error. WebsiteStatus displays the exact code returned so you can diagnose the issue.
