Compare uptime
You can view all monthly uptime and response time results for a host on its review page (just click the links below).
Uptime is a measure of the availability of a web server over a given period of time.
When a website goes “down” (becomes unavailable) it’s referred to as “downtime”. Downtime can impact and organization’s reputation, search rankings and revenue.
We maintain hosting accounts with some of the world’s largest shared web hosts and monitor the uptime and response time of these accounts on a second-by-second basis.

What’s the impact of downtime?
When looked at over a timeframe of one month, 0.01% of downtime (99.99% uptime) equates to 4 minutes and 23 seconds of downtime; however, over one year it equates to roughly 53 minutes.
More uptime and downtime calculations:
- 99.90% (month): roughly 43 minutes of downtime
- 99.90% (year): roughly 8 hours and 45 minutes of downtime
- 99.00% (month): roughly 7 hours 18 minutes of downtime
- 99.00% (year): roughly 3 days 16 hours of downtime
There are other things to keep in mind:
- When advertising uptime guarantees, most web hosts will display a 99.90% uptime guarantee as a 99.9% uptime guarantee. Likewise, when advertising an uptime guarantee of 99.00% many display the guarantee as 99%.
- Behind most uptime guarantees is an which compensates customers for downtime; however, there are often numerous caveats and some web hosts won’t rely on third-party monitoring software to determine whether their servers were available.
- Most web hosts set time aside for what’s referred to as “scheduled maintenance”. On this basis, some downtime should be expected, and web hosts often forewarn customers about scheduled maintenance to their servers.
Uptime is distinct from how fast a page loads (page speed) or a server responds (response time). In other words, just because your server is available, it doesn’t necessarily mean it responds to requests quickly.
- Uptime: is the server available?
- Response time: how fast does the server response to requests?
- Page speed: how many assets (files, images, scripts, etc.) must be served for a page to load in full?
