What is the default response time for Siteimprove to report the site being down due to timeout?

The Response module checks the response time of a website every 5 minutes by default, or by intervals, you select in Response settings. The default response time for Siteimprove to report your website being down due to timeout is 30 seconds. This can be changed based on your preferences in Response settings.

Siteimprove reports a site being down due to timeout when your site is reported down from two different server locations. Only one "good check" is needed to report a site up again.
