Whether links fail because of DDoS attacks, censorship, or just plain old link rot, reliably accessing linked content is a problem for Internet users everywhere. The more routes we provide to information, the more all people can freely share that information, even in the face of filtering or blockages. Amber adds to these routes.

Amber automatically preserves a snapshot of every page linked to on a website, giving visitors a fallback option if links become inaccessible. If one of the pages linked to on this website were to ever go down, Amber can provide visitors with access to an alternate version. This safeguards the promise of the URL: that information placed online can remain there, even amidst network or endpoint disruptions.

Lots of copies keeps stuff safe. By default, Amber stores snapshots directly on the host website. But users can choose to store snapshots using a combination of the following third party storage and archiving systems: the Internet Archive,, and Amazon Simple Storage Service (Amazon S3).

Amber is an open source project led by the Berkman Klein Center for Internet & Society. It builds on a proposal from Tim Berners-Lee and Jonathan Zittrain for a “mutual aid treaty for the Internet” that would enable operators of websites to enter easily into mutually beneficial agreements and bolster the robustness of the entire web. The project also aims to mitigate risks associated with increasing centralization of online content.
