Someone needs to learn how to read the Bot Traffic page.
That is a drop in traffic specifically from Yandex bots (which includes their crawlers and other apps hosted in their DC)
Now compare it with Bot Traffic in:
* Russia: https://radar.cloudflare.com/bots/ru?dateRange=7d
* Europe: https://radar.cloudflare.com/bots/europe?dateRange=7d
* Worldwide: https://radar.cloudflare.com/bots?dateRange=7d
Dip is barely noticeable even in Russia.
Its like saying, "API requests are completely down" (and small disclaimer: only from your server, because your server is down)
Don't worry, now that Trump started protecting the refineries, the other data centers will be hit sooner rather than later. All those fresh fp2 drones can't go to waste. The only question is whats next - power plants? Water treatments? Heating somewhere up north?
Absence of bot traffic is secondary to the absence of nearly all Yandex traffic in general, bot or not, as a result of the datacenter being down. Which is certainly newsworthy.
Your initial submission title sounded as if Yandex DC was used as a bot attack and because they were down, bot traffic in the whole internet was substantially down.
