Uptime guarantee refers to the percentage of time your hosting provider promises your website will be available.
Common Uptime Guarantees:
- 99% uptime = up to 7 hours of downtime per month
- 99.9% uptime = less than 45 minutes of downtime per month
- 99.99% uptime = only 5 minutes of downtime per month
For businesses, uptime is critical since downtime means lost customers and revenue. Always choose a hosting provider with at least 99.9% uptime guarantee.
