How to understand why Rostelecom has blocked the site?

I first came across a website that was in the register is prohibited. And ironically it was one of my sites.
The usual site of a small commercial company providing consulting services.

I have mobile Internet from Rostelecom, and so it turned out that the website (and the couple next to him) blocked only with Rostelecom.
In the registry of banned sites, neither domain nor IP is not found, but the site is still blocked.

What would you recommend to do?

UPD: Everything is already decided, most likely the host itself solved the problem.

If you have shared hosting, the site of the culprit, was able to remove with hosting, also deleted it from the registry, but Rostelecom may slow down.
In any case, contact your hoster, he most likely knows who the culprit is.
It seems the hoster has already solved the problem, thanks. - Cecile_Wilkinson commented on October 3rd 19 at 04:10

The site is hosted on shared hosting? ie possible Rostelecom blocked the IP for all sites hosted on it from your provider.

What to do? At least angrily to refer to the culprit... in writing (paper, mail of Russia, with confirmation of receipt, personally to the chief/...), phone call etc. just contact your Internet provider and your hosting provider! They too can be informed and also to contribute its share in solving the problem.

It is clear that almost certainly nothing will change. But, if only to remain silent, nothing will change and so will the shown active position and maybe something will change for the better.
Everything resolved itself, most likely the host itself had settled the matter with Rostelecom. - Cecile_Wilkinson commented on October 3rd 19 at 04:12
