Hi! After a update ip adress from, two days the my site(www.cgkey.com ) does not work.

The thing is that the dns are not propagated for your domain.
We'll do our best in order to help you but it'll take some time.
Evrything will be working correctly during the next 24-48 hours.
We are really sorry for the inconveniences we caused you.

Best regards,
Slavik Koshelev

Thanks Slava!

As I can see DNS zones were fully propagated.

Your domain is working now.
