Upcoming Change to IMS Domain
Effective April 1, 2024
This is an important notice for organizations that are referencing hardcoded imsglobal.org XSDs in your software.
Effective April 1, 2024, 1EdTech will automatically redirect all traffic from its previous domain, http://www.imsglobal.org/, to https://www.imsglobal.org/.
Starting on April 1, we will redirect all files located on www.imsglobal.org to the new secure website—they will no longer be available via HTTP. This change will impact XSDs as well as other files.
The imsglobal.org will eventually be deprecated and go away completely.
Please check any URLs currently resolving to www.imsglobal.org and change them accordingly. XSDs are already located at the secure location so that testing can begin immediately.
We are implementing this change to ensure that we follow best practices. You should not have any issues if you properly respect the 301 redirect protocol by W3C.
1EdTech’s technical staff are available to help with questions.

Update http to https accordingly.
