Fake Yandex bots for real Yandex

Hello.

Starting from 23rd of April’20 a Yandex bot subnet 77.88.5.0/24 is blocked by WAF with the rule set 100203 (Fake Yandex bot).

It is a very frustrating situation, which rises the question of danger of all website been pessimized by this search system, which is unacceptable.

Whose fault is that? Does Cloudflare need to update its search systems IP ranges, or is it a Yandex problem with it bots? (maybe they are somehow broken, I don’t know)

Okay, thank you. The ticket number is 1876913.

Also, I have now an answer from Yandex (there is a TYPO in my ticket. Not “for Yandex”, but “from Yandex”)

Here is the translation:


We have checked the IP address you’ve mentioned, and at first glance, there is no any error with it. We don’t have any list of all IP addresses, which we could give to webmasters or hosting providers. That is because we utilize many IP addresses, and they are changing constantly. Moreover, differnet services of Yandex.ru can use different IPs. We recommend that you check our IPs with User-Agent + Reverse DNS lookup, as it’s described on our Help page https://yandex.ru/support/webmaster/robot-workings/check-yandex-robots.html.

We see, that this IP is fully complied with our documentation, as well as the other IPs. Thank you for the notice, we will try to keep in mind your case with Cloudflare. Could you talk to Cloudflare please also? What is the reason for that blocking action. It could help us understand faster is it required to change anything on our side.
