Wikipedia has banned Archive.today and begun removing nearly 700,000 archive links after the service allegedly DDoSed a blog and was found to have tampered with archived web snapshots. For one of the internet's most-used citation and preservation tools, this is catastrophic. But the alternative—trusting an archive service that weaponizes access and alters records—is worse.

Archive.today (also known as archive.is) has been a critical tool for Wikipedia editors for years. When a source URL goes dead—which happens constantly on the internet—having an archived copy means the citation remains verifiable. Link rot is a serious problem for any reference work, and archive services are how we fight it. Wikipedia alone had nearly 700,000 Archive.today links embedded in articles.

But Archive.today apparently decided to take sides in an internet dispute. According to reports, the service executed a distributed denial-of-service attack against a blog. That's not archiving—that's a weapon. And when an archive service decides to weaponize its infrastructure against users, it's no longer trustworthy as a neutral preservation tool.

The DDoS attack alone would be damning enough. But investigators also found evidence that Archive.today has been tampering with web snapshots—altering the content of what's supposed to be a faithful record of historical web pages. The entire point of an archive is that it preserves things as they were. If the archive is changing records, it's worthless.

Think about what that means. Thousands of Wikipedia articles relied on Archive.today links as citations. Researchers used those archives to verify historical claims. Journalists referenced them to prove what a website said at a particular point in time. If any of those snapshots were tampered with, all of that verification is compromised.

Wikipedia's decision to blacklist the service is defensible, even necessary. You can't build an encyclopedia on sources that might have been altered. But it creates an immediate practical problem: what happens to the 695,000 existing citations that relied on Archive.today?

Wikipedia editors are now tasked with finding alternative archives for those links—checking archive.org's Wayback Machine, webcitation.org, or other services to see if archived copies exist elsewhere. For links where no alternative archive exists, the citations become unverifiable. That's a massive blow to Wikipedia's reliability.

The broader lesson is about the fragility of internet preservation. We've built an entire ecosystem around the assumption that archive services are neutral, trustworthy, and permanent. Archive.today just demonstrated that those assumptions are wrong. A single actor running an archive service can decide to alter records, attack critics, and undermine trust in historical preservation.

This is a solved problem, in principle. Decentralized archiving, cryptographic verification of snapshots, and multiple redundant archives could ensure that no single service can compromise the historical record. But those solutions require coordination, funding, and technical infrastructure that mostly doesn't exist yet.

In the meantime, Wikipedia—and everyone else who relied on Archive.today—has to clean up the mess. Nearly 700,000 links need to be reviewed, verified, and potentially replaced. That's thousands of hours of volunteer work to fix a problem caused by one archive service deciding it could weaponize and tamper with the historical record.

The internet needs reliable archiving. What it doesn't need is archive services that DDoS critics and alter snapshots. Wikipedia made the right call, even though it creates an enormous amount of work.

Preserving the truth of the internet is hard enough without the preservation tools actively undermining that mission.
