There are some issues with the HSPc Control Panel this morning that are causing it to display the message;

Server is temporarily closed for maintenance

Server is currently undergoing maintenance and upgrades by our technical support team.

We apologize for any inconvenience this may cause you and thank you for your support as we continue to enhance and improve our software and services.

Thank you.
