To determine the rankings, we monitor the performance of 18 of the world’s biggest web hosts on a second-by-second basis using third-party monitoring software. All selected web hosts are monitored for uptime and response time.
Uptime is a measure of the availability of a web server over a given period of time, while response time is a measure of how long it takes a client to retrieve the first byte of data (TTFB), load HTML and receive HTTP headers.
Response time is not the same as page load time, with the latter being a measure of how long it takes to load all of a page’s assets or dependent files.
GoDaddy, which has maintained uptime of 100 percent for 3 months in a row, slipped in this month’s rankings after maintaining uptime of 99.98 percent.

When analyzing the data it’s important to account for variables like scheduled maintenance (the conditions surrounding this are typically outlined in a web host’s terms and conditions).
It’s also important to note that uptime and response time are merely two of many factors that should be considered when evaluating a web host’s performance.
