Wikipedia editors have officially blacklisted Archive.today, ordering the immediate removal of over 695,000 links to the service across the encyclopedia. The decision follows serious allegations that the archiving platform, which includes domains like archive.is and archive.ph, has been weaponized to conduct DDoS attacks and has actively tampered with stored web content.
From Research Tool to Security Risk
Widely utilized by Wikipedia contributors to bypass paywalls and preserve citations, Archive.today has now been deemed a security liability. According to the official Wikipedia discussion page regarding the ban, the community consensus is clear: the site can no longer be trusted as a reliable source of information.
This is not the first time the site has faced scrutiny; it was previously blacklisted in 2013 before being reinstated in 2016. However, the current evidence of malicious behavior has rendered its past utility irrelevant.
Weaponized JavaScript and Content Manipulation
The primary catalyst for the ban involves a distributed denial-of-service (DDoS) attack allegedly launched against blogger Jani Patokallio. Investigations revealed that users visiting the archive’s CAPTCHA page were unknowingly executing JavaScript code designed to flood Patokallio’s site with search requests, effectively driving up his hosting costs.
Allegations of Tampering
Beyond the DDoS attacks, Wikipedia editors have documented instances of altered web snapshots. The site’s operators are accused of manually injecting names and content into archived pages, fundamentally compromising the integrity of the historical record.
A History of Hostility
Tensions between the platform’s mysterious operator and Patokallio escalated after the blogger published a deep dive into the site’s ownership. The archive’s webmaster reportedly demanded the removal of the post, later resorting to threats when the request was denied, as evidenced by leaked email correspondence.
While the site’s owner remains largely anonymous—often described as an individual with high technical proficiency—the operator acknowledged the situation on a linked blog, stating they would “scale down the ‘DDoS’” while mocking mainstream media coverage of the event.
Next Steps for Wikipedia Editors
Following the new guidance, Wikipedia editors are now tasked with scrubbing the site of all links to Archive.today. Contributors are encouraged to replace these references with links to original sources or verified, stable alternatives such as the Wayback Machine to ensure the long-term reliability of the encyclopedia’s footnotes.
