02 Feb 2021

Downtime Monkey now logs more than 4 million website responses each day. We analysed these to see how fast websites respond in practice.

1 Million Response Times Analysed

We collected 1 million response times from real websites. Half a million from Pro plans and half a million from Free plans.

We then split these into groups: 0 to 1 second, 1 to 2 seconds, 2 to 3 seconds etc. and then counted the number in each group. For responses slower than 17 seconds a site is considered down.

Here are the results:

Fastest Websites Analysed

The majority of sites responded within a second, so we took another sample and broke the fastest sites into groups of a quarter of a second.
