Wikipedia has blacklisted Archive.today and begun removing over 695,000 links to the archival service from its pages. The decision follows concerns that Archive.today tampered with archived web snapshots, potentially compromising the integrity of historical records. This move affects Wikipedia's vast repository of cited sources, as the site relied heavily on Archive.today for preserving web content that might otherwise disappear.

Archive.today, formerly known as Archive.is, provides permanent snapshots of web pages, allowing users to preserve content even after it's removed from the original site. The service has been a crucial tool for journalists, researchers, and archivists. Wikipedia's action represents a significant blow to Archive.today's credibility and utility, as losing access to Wikipedia's massive traffic and citation network could substantially impact the service's reach and influence.

The removal process is already underway, with Wikipedia editors systematically replacing Archive.today links with alternative archival services or removing dead links entirely. This development highlights the ongoing challenges in maintaining reliable digital archives and the importance of trust in archival services. Wikipedia's decision underscores the delicate balance between preserving web content and ensuring the authenticity of archived materials.
