If you go to http://www.intodns.com/ and enter your domain name there you can see if any errors are returned. Sites like intodns.com and mxtoolbox.com are designed to be reference guides only, they are not authoritative. So even if errors show up here, if there are no problems with your domain services and functionality, there is no need to change anything. However, we have noticed that users in some markets such as Australia .com.au domains are experiencing periodic problems while using the round-robin DNS (yin.ssl1.us and yang.ssl1.us).
It appears that the .au authority is implementing changes in standards recently that effectively drops support for our round-robin style dns/nameservers system. For best results, we suggest changing the nameservers.
Here is how:
(If your domain name is registered with us, simply open a ticket requesting nameserver change and we will take care of everything for you)
=== HOW TO CHANGE NAMESERVERS FROM ROUND ROBIN TO STATIC
1) Log in to your domain name registrar. Navigate to the "Nameservers" management area. Edit the nameservers:
Replace with these
Save the changes.
2) Open a support ticket listing the domains you require changed and we will make the appropriate corresponding changes to namesevers on the server DNS.
You will not experience any downtime or disruption of service because we are not changing server or IP address.
