Are Yandex ad units connected to Google Adsense?

Question

contextual advertising

I installed advertising from Yandex on my sites, then accidentally measured the site loading speed in the www.webpagetest.org service and was unpleasantly surprised - the site began to load twice as long.
As it turned out, Yandex ad units connect to Google servers and, as I understand it, they sometimes show ads from there. I wrote in support of YAN, but everything is denied there. But there is a fact, when I check any page with advertising, a bunch of connections with google appear, when there is no advertising, there is no Google either: Maybe I don’t understand something, I didn’t find an answer on the network, maybe you know?

Answer 1

By the way, detailed statistics show that everything is loaded from https://yandex.ru/set/s/rsya-tag-users in the photo.

Answer 2

I confirm! I have the same redirects on itcrumbs.ru . I remove the RTB blocks, everything is clean ... Maybe someone has already figured out how to get rid of them?
