urls not working

http://archiveexperiments.pages.archivelab.org (item)
http://wayback-timemachine.pages.archivelab.org (item)
http://freefakebooks.pages.archivelab.org (item)
http://iiif-bookreader.pages.archivelab.org (item)

Start by checking the four listed URLs—archiveexperiments, wayback-timemachine, freefakebooks, and iiif-bookreader—to confirm how they fail, then inspect the repository's proxy entry point. Done means identifying and fixing the shared cause so each listed pretty URL loads its corresponding archive.org page.
