Strange Update To Facebook Causing More Traffic To Pages

Has anyone else noticed that in the past week some change to Facebook's algorithm(s) have caused old pages, often pages that have been dead for years with little followers, to receive out of the ordinary traffic resulting in new likes and shares? I have. I doubt I'm alone in this. Something has happened. I'm not exactly sure what it is but I intend to figure it out. If anyone knows anything or has any ideas, lets hear about it.

I'll update this thread if I find out anything more.
