Website Uptime Monitor
Instantly check if a website is up or down, its HTTP status code, response time and server headers.
How to use this tool
- Enter your website URL. Include https:// or just the domain name.
- Run the check. We send a live request from our server and measure the response.
- Read the status. Look at the HTTP status code, response time and server headers.
- Fix slow responses. If the response is slow, move to faster NVMe hosting from QW HOSTING.
Free website uptime and response time checker
Downtime costs sales, damages trust and can drop your Google rankings if crawlers repeatedly hit errors. This free QW HOSTING uptime tool makes a real HTTP request to your website from our server and reports the status code, response time, server software and caching headers — with no account and nothing stored.
What the status codes mean
- 200 — everything is fine.
- 301 / 302 — a redirect; check that it points where you expect.
- 403 — the server is blocking the request, often a firewall or ModSecurity rule.
- 500 / 503 — a server-side error, exhausted PHP memory or overloaded shared hosting.
- 522 / timeout — the server never responded, usually resource limits at a cheap host.
Frequent 500 or 503 errors normally mean your current hosting is overloaded. QW HOSTING shared cPanel hosting runs on NVMe SSD storage with LiteSpeed and generous resource limits, and migration is free.
Frequently asked questions
Is this uptime checker free?
Yes. It is completely free with no signup, no account and no database. Enter a URL and check instantly.
Do you store my monitored websites?
No. QW HOSTING stores nothing. Every check runs on demand and results are discarded once the page is rendered.
Why does my site show as down when it opens for me?
Your browser may be loading a cached copy, or the server may be blocking datacentre IPs. Check the HTTP status code shown below for the exact reason.
What is a good server response time?
Under 200 ms is excellent, 200-600 ms is acceptable, and above 1 second will hurt Core Web Vitals and rankings.
Can I get continuous monitoring?
This page is designed for manual checks. QW HOSTING hosting plans include server-level monitoring and our team can set up scheduled alerts for business customers.
