How does it work

We check the status of a website by doing an HTTP GET request

If the status code is in the 200 or 300 range, the site is considered online.

Codes in the 400 or 500 range indicate potential issues.

Any other code, or no response, is interpreted as offline.

The number next to the icon indicates the response time in milliseconds.
