I had the same problem as yours but i got the answer on it like 1 hr ago.
starka server will be online again as soon as the DNS propagation is done. This could take some time.
By this time you can access to the cpanel from this link:
http://www.[website address]:2082
Replace [website address] by your website address.
example:
http://www.example.x10hosting.com:2082
This way you will have access to you cpanel.
Also your website might needs some modifications.
Go to your config.php or whatever you named it and change the server directory from :"mysql-starka.x10hosting.com" to "localhost"
This will resolve the mysql problems and your website should come back online again
