The CIS Alert Level is a representation of the current state of cyber(in)security, globally.

There used to be a history of the levels, with an explanation for the changes (especially the rises). I cannot find it anymore - would someone know where it is currently hosted?

Note: I am aware of the subjectiveness of this or another measurement for "cybersecurity threat". I would be glad to use others, for the sake of completeness but I am currently especially interested in the historical aspects of the changes.
