Thank you for contacting Online Support. After reviewing your account your domain and hosting are configured and functioning properly and resolve to a live site to the correct IP address, and your Admin login page loads correctly.
In reviewing your site we are currently unable to duplicate the issue you are experiencing. I have also tested your hosting plan and am able to confirm that there are no known issues that would cause what you are describing.
We understand this does not signify that no issues exist but without being able to duplicate what you are describing it is extremely difficult to verify the root cause of the issue. If you are seeing this occur intermittently, and believe this is related to a server-specific issue, we recommend that you contact our Support team by phone when the problem is occurring. This will allow us to troubleshoot the issue in real time.
If you would like us to review your issue further please provide additional information regarding your current issue including any error messages, domain names, screen shots or URL’s related to the incident. Please also try to reproduce your issue through another network and Internet Service Provider.
