How to access Wikipedia during the blackout
The Wikimedia foundation have a technical description of how the blackout is implemented here.
Added: the stylesheet itself appears to be at http://bits.wikimedia.org/en.wikipedia.org/load.php?debug=false&lang=en&modules=site&only=styles&skin=vector&* so blocking that temporarily might help.
If you are managing a large number of users who need access, you can block access to bits.wikimedia.org/en.wikipedia.org/ which will allow access to content but screws up the layout.
