How to fix: a site that has been on the domain for a long time is displayed?

Question

Domain Name System

The domain was bought on nic.ru
DNS servers dns1.yandex.net and dns2.yandex.net
2 months have already passed.
From Russia, the correct one is displayed, and some European visitors see the old version of the site, which is on a different server.

Answer 1

And what were the DNS servers of the domain before?

Maybe similar to your situation?

Answer 2

Svetlana, the question is of course stupid, but how much time has passed since the DNS records were changed?
Probably DNS propagation has not worked yet, and old IPs are visible.
Look up your site through the DNS Propagation utility. For example: https://www.whatsmydns.net/
PS. 48 hours is the maximum time for updating records on all DNS servers.
