What is Uptime & Error Rate?
Uptime measures the percentage of time a website or service is available and accessible to users. A 99.9% uptime means the site is down for about 8.76 hours per year. Error rate is the percentage of requests that result in HTTP errors (4xx, 5xx). Monitoring these metrics helps you:
- Maintain user trust – Frequent downtime drives visitors away.
- Improve SEO – Google considers site availability in ranking.
- Optimize performance – Slow response times hurt conversion rates.
- Meet SLA commitments – Essential for businesses with service level agreements.
