I created the DNS records with the instructions given by creating a page from the Pages section and adding a custom domain.
I live in Turkey, the system works ideally for Turkey.
I asked my friend who lives in Poland to test the web page.
He posted a video like this: https://turizmhosting.com/poland.mp4
I also asked my friend who lives in Australia to visit the web site. said the page did not open.
What I said above applies to Custom Domain.
