According to Google,
A DNS error means that Googlebot can’t communicate with your DNS server either because the server is down, or because there’s an issue with the DNS routing to your domain.
This most often happens due to your webhosting shared hosting account.
You don’t need to swtich back to old domain, this is a normal error which occasionaly occures when your server is overloaded. Contact your webhost when this error displays again, for the time being you can ignore it because your site DNS settings is well setup and it is indexed well too.
