Possible reasons for website unavailability
Site24x7 monitors the availability of your website by sending an HTTP request to the webserver and checks the status code of the returned response. A 200 OK success response indicates that the website is available. We will consider a website as unavailable due to several reasons. Some of the major ones are listed below:
- When the website is not accessible
- In cases when the response time of the website crosses 30 seconds (Note: You can check your web server access logs: User-Agent: Site24x7 to corroborate this.)
- If the HTTP Response code is 4XX or 5XX
- In case of authenticated websites, mismatch or invalid username/password
We will change the status of the website monitor to "Down" for all the above reasons and trigger an alert notification.
