What is Uptime and Why is Uptime Monitoring Important?
What exactly is uptime, why does it matter, what constitutes a good uptime percentage, and is 100% uptime achievable? We’ve compiled answers to some of the most frequently asked questions about uptime rates for you.
What is Uptime?
Uptime is a metric that shows how continuously your website operates without interruptions. Naturally, we all expect our websites to be online and functional at all times. However, achieving this in the real world is challenging. Uptime can be defined as the ratio of the time a website is operational to the time it is not. Conversely, downtime refers to the periods when the site is not operational.
For instance, a website with a 99.99% uptime rate is down for 1 hour every 10,000 hours (which is slightly more than a year).
Why is Your Uptime Rate Important?
The uptime rate is critical because it reflects the availability of your service. If visitors cannot access your site when they want to, this directly impacts your business. Worse, during this downtime, potential customers may switch to your competitor’s site.
What Should a Good Uptime Rate Be?
You know your uptime rate, but how do you determine if it’s good or bad? For those unfamiliar with these matters, rates above 99.9% might seem excellent. However, a simple calculation reveals that a site with a 99.9% uptime rate is down for approximately 9 hours a year, which isn’t as great as it sounds.
Many hosting companies claim to offer uptime guarantees, typically between 99.9% and 99.99%. Each nine missing after the decimal point implies that the duration your website is down could increase tenfold. Below, you can find the downtime corresponding to different monthly and yearly uptime rates.
| Uptime (%) | Monthly Downtime | Yearly Downtime |
|---|---|---|
| %99,9 | 43,83 minutes | 8,77 hours |
| %99,95 | 21,92 minutes | 4,38 hours |
| %99,99 | 4,38 minutes | 52,60 minutes |
| %99,995 | 2,19 minutes | 26,30 minutes |
| %99,999 | 26,30 seconds | 5,26 minutes |
