Discover which PoP routed your request

You can see which server location your request has been routed through by checking the site's headers. An easy way to do this is by using cURL, a command-line tool that allows you to transfer data over various protocols such as HTTP, FTP, SMTP, and others. cURL is built into the terminal on macOS, and is available on current versions of Windows 10. Here's how to see the server location.

  1. Open Terminal on a Mac, or Command Prompt or Git on a PC, and then run the following command:
    curl -IL http://yourdomain.com/
  2. A list of headers will be returned. The header needed to determine the PoP location is x-sucuri-id:

    3. 
$ curl -IL https://sucuri.net/
HTTP/2 200 
server: nginx
date: Tue, 21 Feb 2023 00:53:52 GMT
content-type: text/html; charset=UTF-8
x-sucuri-id: 11016
  3. The number returned from that header corresponds with the firewall PoP your request was routed through.
