Update timeline

  1. identified Oct 22, 2025, 08:52 PM UTC

    We have been receiving reports from customers that their websites are being blocked when end users are using Microsoft Edge in Strict mode. This is due to an incorrect tracker classification for some of Contenful’s domains (cdn.contentful.com). We are following up with the classification service owner to have Contentful domains removed from this list in order to mitigate this issue.

  2. resolved Nov 10, 2025, 01:27 PM UTC

    Over the past weeks, we have worked with the Microsoft Edge team around this incorrect tracker classification. Contentful requests should no longer be blocked when Strict Mode is enabled on Microsoft Edge browser.
