What's the Problem?

Whether links fail because of DDoS attacks, censorship, or
just plain old link rot, dead links are a problem for Internet
users everywhere.

This isn't a new problem.1  Some centralized initiatives, such as
the Internet Archive and Perma.cc, are attempting to snapshot
and preserve the Internet.

But more and more, just a handful of centralized entities
host information online. Online centralization creates
“choke points” that can restrict access to web content.

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.

What Amber Does

What Amber does

Amber is an open source tool for website owners and
administrators to safeguard the promise of the URL: that
information placed online can remain there, even amidst
network or endpoint disruptions.

By automatically storing a mirror of every page linked to on
a website, Amber gives visitors a fallback option if links go dead.

These mirrors are stored directly in the local storage space
of the website or server. If one of the pages linked to on this
website were to ever go down, Amber has stored and can
provide visitors with access to a mirrored version.

Research

Amber is an open source project led by the Berkman 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.

Amber also continues the work completed by students from the
2011-2012 Ideas for a Better Internet4 "Mirror As You Link" group,
which developed working code5 for an extension to mirror
WordPress blogs.

Amber does not collect any sort of data from websites or their
users. It runs solely on your server and does not connect back to us.
