Wayback — facebook.com
The Wayback Machine applied to facebook.com URLs, surfacing archived snapshots of public Facebook pages and posts where they were captured. You check capture existence and open saved copies through its replay links. Coverage is sparse because Facebook blocks crawlers and many captures are only the login interstitial, so results are best for public Pages.
