It’s time to move forward

Link rot refers to the gradual decay of regular web hyperlinks, which over time stop pointing to their originally intended pages because the resources they point to are moved, removed, or become permanently unavailable.

Research on the web has shown that link decay is measurable: for instance, a 2003 study found that roughly one out of every 200 web links breaks each week, implying a half‑life of about 138 weeks. Later analyses have confirmed similar patterns, such as a 2016–2017 study of links in the Yahoo! Directory showing a two‑year half‑life.

For more than 23 years, the ISSI group has remained committed to preserving the integrity of the web by maintaining a stable website and avoiding broken links. Over time, however, the technical challenges of sustaining such a long‑lived legacy system have grown significantly. These challenges have finally made it necessary for us to retire the old platform—fully aware that, as a consequence, many external links to our site will no longer be valid—and move forward with a more modern, sustainable platform for our site.

Even so, we continue to honor our long‑standing commitment to information preservation, and you can access a static, archived version of our old site, which we will maintain for historical purposes and to ensure long‑term access to its contents. In addition, you can also find historical snapshots of the original website in the Wayback Machine.
