Well, it still has a higher chance of being alive than other common alternatives. From my experience, any url put in a CS paper has a very high risk of being dead just a few years after publication. It seems that once the research grant has run out and the researchers have moved on, noone takes on the responsibility of ensuring that the web page is kept alive. Domains and hosting plans are not renewed; universities reorganize their departments and don't map the old URLs to the new ones; or policies change, and personal department hosted web pages for researchers are closed. The solution has to be some kind of independent library service for researchers, like arxiv for data/source code, which is guaranteed to be kept alive.
