A short time ago I posted on here asking anybody for assistance regarding a duplicate content penalty that had resurfaced because Google's new caching system had reinstated very old cached pages.
Here is exactly what happened. Before I started seo work for a client, the previous seo had installed 5 mirror sites, some had links to them. When I first came on board I deleted the content and uploaded a 301 redirect to the main site.
This worked for about 4 months.
The the site dropped well over 100 places in google.
The reason: Google brought back had the old cached mirror copies and applied a duplicate content penalty.
It has taken eight weeks, but it seems we are now cemented back at number 1.
I hope that helps anyone else who is suffering from a similar penalty that they don't deserve.

Google bringing back cached copies from the mirrors was probably a temporary roll-back.
Luke, your "penalty" was probably more a result of Google not passing link pop to your new pages via a 301. Once those "new" pages are thoroughly indexed and have some link pop of their own, they will probably rank well (assuming they are SEO'd akin to the original pages).

we as well as a number of other WMs have experienced a small problem with the same type thing - all related to having many domains pointing at the same domain (stacked/aliased in 'nix) With the splitting of the sites into many pieces we did the same thing with the remove tool and the 301s and some of us are coming back. Went today to try to do the same thing for another friend, and the Google Removal Tool is gone - don't know what happened.
