2011年，网络设计师Jeremy Keith在Long Bets平台上发起了一场关于互联网资源长期可用性的预测赌注[1]。Keith预测相同URL资源难以在11年内保持在原始位置可用，而技术人士Matthew A Haughey对此提出异议，认为现有技术和策略足以维持稳定的URI系统[1]。
这场赌注约定于2022年2月22日进行验证，通过访问特定URL（http://www.longbets.org/601）来确认该网址是否仍能返回包含特定文本的HTML文档[1]。预测背景源于Tim Berners-Lee在1999年提出的"Cool URIs don't change"（优雅的URI不改变）理念[1]。获胜方对应的慈善机构将获得捐款，其中Keith的预测若成立，Bletchly Park Trust将获得赞助；若Haughey的观点被验证，Internet Archive则将获得捐款[1]。
In 2011, web designer Jeremy Keith placed an 11-year prediction on the Long Bets platform, wagering that the same URL resource would not remain available at its original location for the full duration [1]. Keith's specific prediction centered on whether http://www.longbets.org/601 would continue to return an HTML document containing particular text [1]. This wager was challenged by Matthew A Haughey, who took the opposing position [1].
The prediction drew on broader debates within the web development community about URL stability, referencing Tim Berners-Lee's 1999 principle that "Cool URIs don't change" [1]. Keith argued that network resources face inherent challenges in maintaining persistent URLs over extended periods, while Haughey contended that existing technology and strategies were sufficient to sustain a stable URI system [1]. The two sides agreed to resolve their bet through direct access verification on February 22, 2022, when the 11-year period would conclude [1].
The outcome of the wager carried stakes for charitable giving: Keith's victory would direct a donation to Bletchley Park Trust, while a win for Haughey would benefit the Internet Archive [1].
