I was initially worried about end-to-end traffic, but saw that the exit nodes and bridges haven't increased. If Google search traffic is a fair indicator, it looks like genuine user growth is driving this. Google searches for "tor" haven't seemed to move much globally [1] but Russia saw a huge jump starting on August 16th [2].

Anyone know how to get the same info for Yandex to cross-check?
