Updating CDC Links in MedlinePlus

MedlinePlus is in the process of updating its links to content from the Centers for Disease Control and Prevention (CDC) in response to a major CDC website revision. For more information, please see CDC Moving Forward.

This should have a very minimal impact on MedlinePlus Connect users. Direct links to the CDC are returned primarily in the reference list for lab test and procedure code requests to the MedlinePlus Connect Web Service.

If you encounter a broken link on the MedlinePlus website, please report it to NLM Customer Support.

This is a reminder that in January 2023, the MedlinePlus Connect Web Application and Web Service moved to the AWS cloud. As soon as possible, please test your implementation of MedlinePlus Connect using our test page. Currently, we are running parallel systems that support our old IP addresses and new AWS IP addresses. During the third week of June, access to MedlinePlus Connect will be available using the new AWS IP addresses only.

What's changed? The IP addresses for accessing the MedlinePlus Connect Web Application and Web Service have changed.

What do you need to do? If your organization uses firewall rules for accessing MedlinePlus Connect, you need to update your firewall rules to allow for new IP addresses:

IPV4: 75.2.125.67

To help you successfully implement the change, here is a timeline of key dates and actions:

The test page is located at https://medlineplusconnect-test.nlm.nih.gov/ [URL discontinued as of June 23, 2023.]

Please check to see whether you can access the test page from within your implementation. If you successfully access it, you will see a confirmation message at the top of the page. If you cannot reach the test page, it may indicate that security or other technical settings will impede your use of the AWS version of MedlinePlus Connect after mid-June 2023. In this case, please make the appropriate adjustments to your implementation as soon as possible.
