I know of a whole slew of sites that are partly or completely locked out today as a protest to the two bills. It's making things a little more difficult than normal, but that's the whole point.

Gmail, G+ and Google search all work fine for me so at least we still have that, but (imho) it would be nice if google locked out their US search servers today, that would hit just about everyone in congress and the senate pretty hard, maybe they'd all realize that if the bills were passed, they'd all lose their precious google searching too.
