Per the about page, which is linked right at the top of 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.”
