  • RestoredCDC.org
    "We are developing code to pull CDC pages which were archived by prior to January 20, 2025. Similar archives have been created by the End of Term (https://eotarchive.org) project and are hosted by the Wayback Machine (https://web.archive.org). The individual pages are archived, but links between them are broken and the pages are not easy to locate through web searches. Therefore, we will re-build the links between the pages, to create a site that can be navigated the same way the pre-January 21, 2025 CDC site. The only changes we will make on these pages is to add a header that indicates that this site is not a CDC website. Because of the complex navigation between pages, we will also include a button to report problems in this header. Our goal is to provide a mirror site that provides the same information and user experience as the previous CDC website. Some functionality, such as videos, was not archived and therefore will not work on our site."
