Website Availability Checker: Monitor Uptime & Server Health 24/7

Website downtime costs businesses revenue, customers, and credibility. Our Website Availability Checker provides instant verification of your website's status, helping you maintain 99.9%+ uptime and deliver reliable service to your visitors. Website availability (uptime) is the percentage of time your website is accessible to visitors. Industry standard is 99.9% uptime, which allows for only 8.76 hours of downtime per year. Downtime impacts revenue loss for e-commerce sites, SEO penalties from Google, damaged customer trust, SLA compliance issues, and competitive disadvantage. We monitor your website through HTTP/HTTPS requests, response code analysis verifying 200 OK status, response time measurement to track performance, content verification to ensure pages load completely, and multi-region testing to check global accessibility. Common availability issues include server crashes, resource exhaustion, database failures, application errors (500, 502, 503), DNS resolution failures, SSL certificate expiration, DDoS attacks, and configuration errors. Understanding uptime: 99% equals 7.2 hours downtime per month (unacceptable), 99.9% equals 43 minutes per month (standard), 99.99% equals 4 minutes per month (excellent).
