Codehaus shut down earlier this year. Many projects that were hosted there, including JIRA pages like this one, are now broken.
What can I do to access all the lost content of projects that were hosted in Codehaus, such as bug reports? Was it uploaded/dumped somewhere?
Further, since Google Code is also shutting down, a similar problem will probably show up soon. What can be done to prevent the loss of important information like bug reports and wiki pages?
