The Probability of a Web Page Being Accessible After 11 Years
A bet on the transience of the internet and the permanence of URLs.
1The Ephemerality of the Web
Despite Tim Berners-Lee's 1999 statement 'Cool URIs don't change,' the probability of web documents surviving in their original locations decreases over time. This phenomenon, known as link rot, is often described as the entropy of the web. Even a relatively short period like 11 years may not be enough for a resource to remain accessible.
2The Historic Bet
On February 22, 2022, visits to http://www.longbets.org/601 must still contain a specific text. This text states that the original URL will no longer be available in eleven years. Even a 301 redirect would satisfy this condition.
3Institutional Support
The winning party of the bet will be either Bletchly Park Trust or The Internet Archive. These organizations are dedicated to preserving digital information. The Internet Archive, in particular, plays a pioneering role in preserving the web's history.
4Technological Maturity
In over 20 years of web history, technology and strategies have matured. Maintaining a stable URI system is now within reach of anyone with moderate technical knowledge. For example, a 13-year-old website can still maintain its original URL scheme through 301 redirects.
5The Importance of 301 Redirects
301 redirects indicate that a URL has permanently moved to another address. This method is an effective solution to prevent link rot. For instance, even if a website changes its format, old URLs can be redirected to new addresses.
6Web Archiving Efforts
Organizations like The Internet Archive strive to preserve the web's past. Tools like the Wayback Machine save old versions of pages that are no longer accessible. These efforts contribute to the preservation of digital cultural heritage.
7Long-Term Digital Preservation
The long-term preservation of digital information carries technological and organizational challenges. Institutions and individuals need to become more aware of this issue. Regular backups and proper redirection strategies can prevent data loss.
8Digital Cultural Heritage
The disappearance of web pages means the loss of a part of our digital cultural heritage. Therefore, the permanence of URLs is not just a technical issue but also carries cultural significance. Preserving the web as it is today for future generations is a collective responsibility.
