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,
Perma.cc, 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.

Version 1.4
Release date: December 7, 2015
We're in the WordPress plugin directory! New and improved in Amber v1.4 for WordPress:
- Storage of snapshots in other locations. You can now choose to store snapshots on one or more third party storage and archiving systems: the Internet Archive, Perma.cc, and Amazon Web Services (S3). You can enable this feature to free up space, take advantage of donated host space, or simply to contribute to existing web archival efforts. Remember: lots of copies keeps stuff safe!
- Display of snapshots from other archives. Amber can now also display to your visitors alternative versions of a URL from other archives, including the Internet Archive, the Library of Congress Web Archive, Archive-It, archive.is, Webcite, and more. If enabled, you can display to your visitors the Amber snapshot in addition to other available versions of the same page--providing even more routes to linked content. This is made possible through expanded support of the Memento protocol and the Memento project's "time travel" and "TimeGate" concepts.
- Compatibility with academic efforts to retrieve more accurate data. This release defined parameters for Amber users to benefit from academic research efforts on Internet activity and content controls. The Berkman Klein Center's Internet Monitor project compiles and curates quantitative data to give policy makers, digital activists, and researchers. Primary data collected by the Berkman Klein Center and our partners, as well as relevant secondary data, will one day help answer the difficult question of "Which URLs are down for whom, where, when, and why?" While such a complete system is not in operation right now, eventually users of Amber can enable this feature to benefit from (by retrieving and contributing) such data.
