How privacy works

Private lookups are not added to public searches, stored reports or change history. This does not remove a report that was already public. Your choice lasts for this browser session.

Who hosts x.com?

Answer

x.com sits behind Fastly, which hides the server that really hosts it.

Host hidden

Checked yesterday from Cloudflare MRS in 286 ms. This is a saved result.

The site is behind a proxy and its pages do not reveal the platform underneath.

Your next steps

What needs attention

Prioritized observations from this check. Review changes with whoever manages the website.

  1. Improve

    Review browser security headers

    Content-Security-Policy, Permissions-Policy did not meet the conservative header checks. This is not a complete security audit.

    Next step: Review these headers with the site developer and test policy changes before enforcing them.
