DuckDuckGo gained a lot of popularity since the Snowden revelations as it allows anonymous searches leaving no traces. Apparently China does not like it.
It is also likely that the number of DuckDuckGo users increased since Apple’s iOS 8 now added Duckduckgo support in Safari as default search engine.
