I would just quickly say that we don't feel that we prevented Canadian users from seeing news. There are lots of different ways they could see news, but there was less appearance of news on our services.
I would say that I'm primarily made aware of tests that involve compliance with laws around the world. That could be the news sites in Spain, the Street View in Germany, the Australian situation or this situation. As Richard mentioned, we run thousands of tests every year, so it would be a relatively small percentage.
