The zone entry for circuitrunners.com no longer contained soap.circuitrunners.com.
I've restored it and everything should be back up and running. If not, try clearing your DNS cache or waiting for it to expire.
Code:
> soap.circuitrunners.com
Server: ns1.sevaa.com
Address: 63.247.91.186
Name: soap.circuitrunners.com
Address: 66.98.242.80
If something like this happens in the future, someone form soap should submit a helpdesk ticket via
