All other servers will be available throughout the maintenance. The maintenance occurs because the US IP addresses will be removed.
Henceforth, VPN05 will only be able to assign Swedish IP addresses. After the update, the VPN05 IP address will be changed to 46.227.67.140. If you have manually entered the previous IP address in your VPN client, you must change. If you have not entered the IP address manually, no configuration change is required.
