On the morning of 09/01/2015 we will have a very short service interruption which will affect VPN02-VPN05.
The reason for the service interruption is that we need to apply an update on our servers to prevent a block that happen between connected clients and devices that are using the add-on service Public IPv4.
VPN01 will be available during the entire service interruption.
The service interruption will be very brief since only the OpenVPN processes need to be restarted.
