This test is performed by measuring the % uptime of a host. Higher is better.
I use Pingdom to report website uptime. Pingdom is configured to make an HTTP request to the host every minute, and report if it is unreachable. It'll also report an error if the host takes longer than 30 seconds to respond (Yes, that's not actually down, but if your site takes that long to respond it is unusable in my opinion). Pingdom performs this test from at least 3 servers worldwide, and reports a problem if 2/3 servers do no respond.
This test is important if you are concerned about the reliability of your web host (this is important!)

DreamHost (full benchmark) performs great in the Uptime test, with an average result of 99.98 percent. Its best run was 100.00 %, but has been as bad as 94.93 %. DreamHost's most recent result on Apr 26 was 100.00 percent. Dreamhost has had a few significant outages, but I've seen worse. Their ping response time is pretty impressive, faster than most hosts, showing they have a decent network.
HostGator (full benchmark) performs incredibly in the Uptime test, with an average result of 99.97 percent. Its best run was 100.00 %, but has been as bad as 97.50 %. HostGator's most recent result on Apr 26 was 100.00 percent. Back in 2013 HostGator had several outages that lasted days. While I wasn't recording detailed stats at the time, I can vouch that it was a miserable experience. Many blame the lack of reliability on their new data center, which they made everyone move to after they were bought out by EIG. To be honest, HostGator's downhill performance was the reason I created this site (I was too annoyed by them to let them get away with it).
InMotion Hosting (full benchmark) performs impressively in the Uptime test, with an average result of 99.96 percent. Its best run was 100.00 %, but has been as bad as 93.68 %. InMotion Hosting's most recent result on Apr 26 was 100.00 percent. When InMotion goes down, they typically are unavailable for only a minute or two. That's alright in my book. They're one of the only hosts that lets you know ahead of time of upcoming maintenance, and how long you can expect your server to be unreachable. I appreciate the communication.
