Yeah, most of the traffic drop was attributable to search spiders not running, not bots. Yandex is a state-captive search engine.

Routing of bot and troll traffic is almost certainly more diverse than that. There's no readon it should be concentrated in specific data centers.

Having said all that, though, it'd be a happy day in my life to find out that some botnets were taken down or, better yet, some troll farms got droned.
