Everything about website downtime
How do I know if my website is down?
Paste the URL in the checker above. Because the check runs from a neutral network (not your computer), you find out whether the site is offline for everyone or just for you. Answer in 5 seconds with HTTP status, response time, server IP and DNS.
Why is my website down?
5 most common causes: (1) hosting server crashed, (2) domain expired, (3) SSL certificate expired (browser blocks it), (4) DNS pointing to wrong IP, (5) server firewall blocked your IP. The diagnosis above shows which one is happening.
Is a website being down a hosting problem?
Almost always yes. Cheap shared hosting typically offers 95-98% uptime (up to 14 hours of downtime per month), while professional hosting delivers 99.99% with a contractual SLA (43 minutes per month). If it goes down frequently, it is the hosting.
Is it down just for me or for everyone?
The checker runs from an external neutral network. If the tool can access the site normally but your browser cannot, the issue is local: cached DNS (run ipconfig /flushdns on Windows or restart your router), ISP block, or browser cache (Ctrl+F5).
How do I get 24/7 monitoring for my site?
This tool performs a one-time check. For continuous monitoring with automatic e-mail and WhatsApp alerts, Rollin Host paid plans include active per-minute monitoring with a contractual SLA of 99.99%.
