If you get a link for a fic and the link doesn't work, try using the Internet Archive Way Back Machine.
Go here:
http://www.archive.org/index.phpAnd paste the URL (with the http://) in the Search box on the page.
You may/will be presented with archive dates for the URL.
Note, the archive dates are a point in time.
You may need to try a variety to find what you are looking for.
The internet archive is not foolproof and doesn't have everything.
Also, if the fic that you are looking for is not in HTML, but rather a database, it may not exist at all.
But this is handy for things like the old "tu lunitics" website which went offline in 2006.
