Uptime Calculator

Uptime refers to the percentage of time a server or service is operational and accessible. For websites and online services, uptime is critical because every minute of downtime means lost visitors, customers, and revenue. A 99.9% uptime guarantee means your website can be down for approximately 43 minutes per month.

Industry standard for quality web hosting is 99.9% uptime or higher. Premium hosting providers often guarantee 99.95% or even 99.99% uptime. At Actiefhost, we maintain 99.9%+ uptime with our reliable infrastructure and proactive monitoring. Anything below 99% is considered poor and could seriously impact your online presence.

Hosting providers use automated monitoring systems that ping servers every few minutes to check availability. These systems track response times and availability over time to calculate the overall uptime percentage. Reputable providers offer transparency through public status pages and uptime reports.

Server downtime can be caused by hardware failures, network issues, software bugs, security attacks (like DDoS), maintenance windows, or power outages. Quality hosting providers minimize these risks through redundant systems, regular maintenance, security measures, and backup power solutions.

This depends on the hosting provider's Service Level Agreement (SLA). Some providers exclude scheduled maintenance from uptime calculations, while others include it. At Actiefhost, we perform most maintenance during low-traffic hours and use redundant systems to minimize impact on your website's availability.

First, use monitoring tools to document the downtime. Then contact your hosting provider's support team to investigate the issue. If downtime persists and violates the SLA, you may be eligible for compensation. Consider migrating to a more reliable hosting provider like Actiefhost, where we offer free migration services and industry-leading uptime guarantees.
