This does not happen very often, but seems to always be at the end of the day or after hours on a Canadian Holiday when IT Support is hard to find. But the dreaded black box has just occurred at the end of a busy day and no IT Support available. I know this is an easy fix, but requires someone from IT support to reboot my server in the Cloud. I wish there was a direct contact available 24 hours a day, 7 day a week that the AC Cloud users could contact for an easy fix. I am unable to do anything when this happens so...... still waiting for IT support to get this fixed.
