Baidu, which is China’s equivalent to Google, has been unavailable since 09:50 this morning, Central European Time. That is more than five hours and counting as of this writing.

The problem might be related to the so-called Great Firewall of China, since it seems like the website is accessible from within China (we performed a test with a proxy server located within China). However, none of the Pingdom test servers in Europe or North America are able to access the site.
