Uptime & SLA – The Reliability Guarantee
Uptime measures how long a hosting server is fully operational and reachable over the internet. It is expressed as a percentage of total time, usually calculated monthly or yearly.
1. What Is Uptime?
- Total Time: 24 hours a day, 365 days a year.
- The Goal: 100% uptime (the website never goes offline).
- The Reality: Even the best servers require occasional reboots, updates, or maintenance.
Because of this, most professional hosting providers — including Jiinubi — aim for 99.9% uptime or higher.
2. The “Nines” of Availability
Small changes in uptime percentages result in big differences in real-world downtime. Here’s what those numbers actually mean over one year:
| Uptime % | Total Downtime / Year | Description |
|---|---|---|
| 99% | ~3.65 Days | Entry-level, unreliable for business |
| 99.9% | ~8.77 Hours | Industry standard, suitable for most websites |
| 99.99% | ~52.6 Minutes | High Availability, ideal for e-commerce |
| 99.999% | ~5.26 Minutes | “Five Nines” – Enterprise-grade reliability |
3. What Is an SLA (Service Level Agreement)?
An SLA is a formal, legally binding agreement between Jiinubi and you. It defines the level of service we promise to deliver — and what happens if we fail to meet that promise.
A typical hosting SLA includes:
- Uptime Guarantee: For example, “99.9% network uptime.”
- Exclusions: Planned maintenance is excluded from downtime calculations.
- Remedies (Credits): Account credits issued if uptime falls below the guarantee.
4. How to Calculate Uptime
You can calculate uptime using this formula:
5. Why Uptime Matters for SEO & Business
Search engines like Google use automated bots to crawl your website. If your site is frequently unavailable:
- Lower Rankings: Google may assume your site is unreliable and reduce visibility.
- User Trust Loss: Visitors who encounter “Server Not Found” errors rarely return.
