As you may have read, Google is now showing messages to users in China, when they try to perform certain queries that it will not work. Users have been getting errors, as illustrated in this video:
Google says the problems are not caused by its own systems, leaving many to assume it's directly related to Chinese censorship, a situation, which ultimately led to Google pulling out its Chinese search engine, and redirecting Google.cn to its Hong Kong search engine. Still it is the Hong Kong version, when used from mainland China that produces these issues.
So now, when users try to enter potentially problematic queries, Google suggests they try an alternative query.
Google's Matt Cutts had this to say about Google's new feature on Google+:
Not everyone is buying the new feature as a "transparent" effort:
@iandanforth this adds a new tool for searchers and clarifies reasons for broken connections that were much more opaque before.
Here's another conversation Cutts had about it on Twitter:
@nelson really, who can say why anything happens in the universe? Maybe a phase-photon particle emitter created a reversal in tachyon force.
You can see for yourself how it works, right here.
