The provider informed me that there will be a scheduled disconnect of the server from the network for maintenance reasons today on 4.21.2015 between 1:00 AM and 2:00 AM CST. The update will improve stability and security.
Since this is only the server being disconnected from the network, there is no risk at all for your stuff on the server. Just please wait until it gets reconnected again. No need to notify my unless the disconnect takes longer than one hour.
