Yandex is Russian Google. Of course they have bots... That's how you index the web.

If we took Google offline I bet there would also be a reduction in bot traffic from them too!

Indexing is also probably a low priority task, so if half their datacenter capacity is taken offline, their bot traffic probably reduces by more than 50%.

I don't think these are the boys they refer to? EDIT: I was wrong, they're just generic bot vs human traffic numbers and you're right
